Beijing’s Reluctance to Engage
On October 24, 2023, a
U.S. Air Force B-52 bomber was flying a nighttime mission in international
airspace over the South China Sea when it was intercepted by a Chinese fighter
jet. In a series of dangerous high-speed maneuvers, the jet pilot flew within
ten feet of the bomber, endangering both aircraft and crews. This came on the
heels of a June 2023 incident when the USS Chung-Hoon, a U.S. Navy
destroyer, was sailing through the Taiwan Strait and a Chinese warship overtook
her on the port side at high speed. The Chinese ship then abruptly tacked and
crossed her bow at 150 yards, causing the Chung-Hoon to slow
her speed quickly to avoid a collision. The Chinese warship ignored repeated
attempts at ship-to-ship communication and violated standard operating
procedures for close encounters on the high seas.
These are but two
near misses in recent years between the U.S. military and the Chinese People’s
Liberation Army. Although U.S. military strategists and planners are
increasingly focused on preparing for intentional Chinese military actions in
the Western Pacific, especially regarding Taiwan,
these close calls have created substantial anxiety among U.S. analysts that an
accident or miscommunication between the U.S. military and the PLA could pull
the two countries into a conflict neither one desires.
PacificDefense.html These concerns are not new. For decades, the United
States has tried to place guardrails on its military relationship with China,
oftentimes borrowing from the playbook it used to keep U.S.-Soviet relations
stable during the Cold War. During the 1990s, when Washington still enjoyed
overriding military advantages over Beijing, U.S. strategists focused on
reassurance, such as military dialogues and communication protocols. Today, as
the Chinese military increases its presence in the Taiwan Strait and the South
China Sea and as U.S.-Chinese tensions simmer from trade to technology, U.S.
officials are more focused on confidence-building measures, which aim to create
greater predictability in military operations, as well as crisis communications
to ensure that a small mishap does not snowball into a full-scale war. China is
the most rapidly growing military and the most rapidly growing nuclear power in
the world. The U.S. has the biggest military in the world,” U.S. Representative
Adam Smith said while visiting Beijing last month. “It is dangerous for us not
to have regular communications about our capabilities and intentions.”
But despite repeated
attempts on the part of U.S. officials to improve military-to-military
communications, the Chinese side has resisted establishing and codifying even
basic rules of the road. Although the reasons for Beijing’s ambivalence have
evolved, what has remained consistent is a deep skepticism that U.S.-led
initiatives will advance China’s interests. It will not be easy for Washington
to overcome such long-standing suspicions. But now that U.S. and Chinese
military capabilities are seen as comparable and the dangers of potential
escalation have grown, U.S. officials looking to reengage U.S.-Chinese military
diplomacy must understand this deep distrust—and then do what they reasonably
can to overcome it.

The Soviet Playbook
U.S.-Soviet military
diplomacy during the Cold War has long served as
a model for successful relations between competing armed forces. Despite being existential nuclear adversaries, the two
states developed significant military-to-military contacts during the latter
part of the Cold War. The 1972 Incidents at Sea Agreement, for example, sought
to prevent ship collisions and reduce the risk of accidental escalation at sea.
The 1989 Prevention of Dangerous Military Incidents Agreement sought to limit
the use of certain weaponry, such as lasers that could potentially blind when
aimed recklessly. These agreements were far from panaceas—U.S. and Soviet
forces did have numerous dangerous and harrowing encounters—but they played an
important role in preempting escalation.
At the beginning of
diplomatic relations between China and the United States in the early 1980s, American strategists tried to apply
these general models to relations with Beijing’s armed forces. At the time,
there were modest military contacts and exchanges, such as meetings on military
doctrine and general training. But these efforts came to an abrupt halt in
1989, when Washington suspended them in response to Beijing’s military
crackdown on protesters in Tiananmen Square.
Relations rebounded slightly in the early 1990s, but not enough to account for
rising tensions. The two militaries were increasingly operating close to one
another, resulting in a series of near clashes, including the October 1994
Yellow Sea incident, when a Chinese submarine and fighter jets patrolled
dangerously close to elements of the U.S. Seventh Fleet, including the aircraft
carrier USS Kitty Hawk. Around this time, senior Chinese
civilian and military officials repeatedly complained to their Washington
counterparts that U.S. reconnaissance aircraft were flying precariously close
to Chinese airspace. They claimed, not incorrectly, that these flights sought
to expose various Chinese air defense systems and operational protocols.
The third
Taiwan Strait crisis, which lasted from 1995 to 1996, brought these issues
to a head. In response to China’s artillery shelling into the waters around
Taiwan, the United States deployed two aircraft carriers to the western Pacific
as a show of force meant to deter any further provocative military posturing on
the part of the PLA. The Chinese, however, interpreted these
actions as deeply humiliating and escalatory, creating substantial mistrust
between the two militaries.
In Washington, the
heightened tensions during the third Taiwan Strait crisis resulted in a
bipartisan consensus around the need to establish military-to-military
communication protocols with Beijing. But U.S. civilian and military leaders in
the Pentagon had other reasons to pursue better relations with their Chinese
counterparts, too. The PLA has long had an important bureaucratic role in
internal Chinese politics, and as the twenty-first century neared, it had a
growing global reach. Forging ties with the PLA’s leaders was thus not only a
way to avert catastrophe but also a way to shape Beijing’s thinking and global
practices.
U.S. efforts to
establish communications reached their high point from 1996 to 1999. In rapid
succession, the two sides launched the 1998 Military Maritime Agreement, which
sought to prevent dangerous naval interactions, and a special leadership
communication channel—a so-called hotline between Washington and Beijing. Both of these initiatives were celebrated at the 1998 summit
between Chinese President Jiang Zemin and U.S.
President Bill Clinton. High-level military officials from the U.S. Office of
the Secretary of Defense and the Joint Chiefs of Staff also began holding talks
with their Chinese counterparts to compare military doctrines in an effort to avoid misinterpreting standard military
deployments and training as preparation for imminent hostile operations. There
were even fleeting exchanges on nuclear-related matters, including the safety
of nuclear warheads and command and launch protocols.

Still, this
engagement went only so far. The two sides had a profound misalignment on the
ultimate uses and value of these communication mechanisms. China was
particularly reticent to make its military too accessible, given the clear
imbalance in military power. After the Cold War, U.S. submarines and
reconnaissance flights conducted missions close to the Chinese mainland,
including in the South China Sea, with greater
frequency and relative impunity. China was overwhelmingly focused on closing
this gap in capabilities and deployment patterns, and its military strategists
viewed U.S. efforts at confidence-building as insincere, designed by
calculating U.S. military interlocutors not to prevent unintended escalation or
conflict but to constrain or monitor China. In this view, formal
confidence-building mechanisms could be used to Washington’s advantage not only
in an immediate crisis but also in the longer term, by giving the United States
channels through which to prevent the PLA’s ambitious buildup.
Chinese officials
still maintained some ties to the U.S. military, which they sought to use for
their own ends, such as limiting U.S. deployments and reconnaissance efforts in
territory immediately adjacent to the Chinese mainland. But Beijing took pains
to keep military exchanges and commitments vague, carefully scripted, and
largely pro forma. Instead of instilling confidence, they worked to create
anxiety and uncertainty in the minds of U.S. operators. This became all too
clear in 2001, when a Chinese jet collided with a U.S. EP-3 surveillance plane
in the South China Sea. When the U.S. plane and
the 24 military service members aboard were forced to land on Hainan Island,
which is home to a Chinese military base, U.S. officials tried to use the
high-level communication protocols but were met with silence and stonewalling
from their Beijing counterparts. Phones rang unanswered as the Americans were
detained for 48 hours of interrogation at a military facility. (They
were subsequently held for 11 days before being released.)
In the decades since,
U.S. anxiety over China’s military modernization and activity has only
increased. Yet if anything, Beijing has become even less forthcoming. The
United States has tried repeatedly to create mechanisms to prevent, manage, or
curtail mishaps in a number of military domains—from
cyberspace to outer space. But these efforts have invariably been met with
misdirection or outright rejection by the Chinese. When U.S.-Chinese
security-related dialogues have been launched, they have failed to live up to
even limited expectations, such as when the Obama administration’s cyber
dialogue failed to limit Chinese hacking. What’s
more, these interactions have often spurred further suspicion and distrust
rather than built confidence. For instance, when U.S. Army hosts took Chinese
counterparts to observe armor training at Fort Hood in Texas, the
visiting Chinese officer subsequently described the briefing and demonstrations
as threatening and designed to intimidate.
China’s reticence is
driven by its deep suspicions. But it manifests in several ways. Beijing, for
instance, persistently fears that bilateral agreements with Washington would
codify China’s inferior military status in perpetuity. From this perspective, a
U.S.-Chinese code of conduct for military encounters gives the United States a
get-out-of-jail-free card, allowing it to continue its freedom of navigation
operations in the region because it can manage risk and extricate itself from a
crisis. The belief that confidence-building measures are
asymmetrically beneficial—that Washington gains more from transparency than
Beijing does—is stubbornly persistent across China’s armed forces.
Historically, China
has also been reluctant to participate in confidence-building exercises
precisely because they were modeled after the U.S.-Soviet experience. This had
less to do with whether these mechanisms were operationally effective and more
to do with how they would be perceived: Chinese strategists astutely sought to
avoid giving the impression that the United States should view China as a
Soviet-like military adversary. This is consistent with broader Chinese
messaging during the early 2000s that sought to downplay talk of China’s “rise”
and instead focus on China’s national “development.”
To some extent, that
has changed: Beijing now wants to be seen as something of a superpower. But
unlike the Soviet Union before it, China does not appear worried about the
escalation risks that come from having poor ties with the U.S. armed forces. If
anything, Beijing seems to see it as a benefit. While Washington generally opts
to telegraph its military acumen, in the hope that its strength gives its
adversaries pause, Beijing largely elects to foster uncertainty in its
deployments, diplomacy, and doctrine—hoping that it increases U.S. forces’
anxiety about operating in proximity. This strategy is largely political.
Although some Chinese analysts and even some PLA officers have advocated for
greater transparency between U.S. and Chinese forces, the leaders of the
Chinese Communist Party have a preference for opacity
about the PLA’s present capabilities and crisis protocols. Ultimately, they
believe ambiguity maximizes their flexibility in a crisis and increases
deterrence.
And what the CCP says
goes: the PLA is the armed wing of the party, not merely China’s armed forces.
The CCP-dominated military structure jealously guards decision-making authority in a crisis and views confidence-building schemes
as a potential threat to party control and authority. Almost by design,
military diplomacy would interfere with the CCP’s control in a military
scenario—precisely when control is most important to China’s leaders.
Senior Chinese
leaders may be downplaying or even dismissing the risk of inadvertent war. The
United States and China, after all, have not experienced serious military
tensions since the latter years of the Korean War. And it may take such
tensions before Chinese leaders change their minds, just as it took the 1962
Cuban missile crisis before Moscow and Washington set up clear
military-to-military ties.
But the United States
should keep pushing to create robust channels of crisis communications before
an emergency occurs. Its efforts may ultimately fall short. Yet with enormous
military firepower potentially arrayed against one another, the two great powers
of the twenty-first century must have the foresight to create such channels
without first subjecting the world to a Cuban missile–type crisis in the
Indo-Pacific.
