US Raises 'Dangerous and Unlawful' South China Sea Concerns in Beijing Talks

In Beijing on Friday, American and Chinese officials sat down to discuss the waters that have become the most volatile flashpoint in their relationship. Mark Lambert, the State Department's China Coordinator, met with Hong Liang, China's Director-General for Boundary and Ocean Affairs, for what both sides would later describe as substantive and candid talks. The conversation centered on maritime disputes—particularly the South China Sea, where competing claims and military posturing have created a landscape of constant friction.

The United States came to the table with specific grievances. American officials directly raised two recent incidents that had rattled Washington: China's obstruction of a Philippine resupply mission to Second Thomas Shoal on October 22, and what the State Department characterized as an unsafe interception of a U.S. aircraft four days later. These were not abstract concerns about regional stability. They were concrete actions, named and dated, that the U.S. side wanted Beijing to understand it viewed as dangerous and unlawful. The State Department's language was notably sharp—not the usual diplomatic softening, but a direct characterization of Chinese conduct as crossing lines.

The timing of these talks matters. They arrive in the shadow of a larger diplomatic effort to stabilize a relationship that has been deteriorating for months. The February downing of a suspected Chinese spy balloon over U.S. airspace had sent bilateral relations into a tailspin, and the two countries have been working since then to rebuild basic channels of communication. This Friday meeting in Beijing is part of that effort—an attempt to keep lines open and, as the State Department put it, to avoid miscommunication and miscalculation. Both sides have reason to want this. The U.S. is pushing hard for a meeting between President Joe Biden and Chinese President Xi Jinping on the sidelines of the APEC summit scheduled for mid-November in San Francisco, though China has not yet officially confirmed it will happen.

Beyond the South China Sea, the talks touched on the East China Sea as well, another body of water where Chinese actions and the interests of neighboring nations collide. But the maritime disputes are only part of what Washington wants to address. The State Department has also scheduled separate negotiations on arms control, with the U.S. Assistant Secretary for Arms Control Mallory Stewart set to host Sun Xiaobo, head of China's Foreign Ministry arms-control department, at the State Department the following week. This reflects a deeper American anxiety: China's nuclear weapons buildup. The U.S. has been calling on Beijing to engage substantively on arms control and strategic risk reduction, but China has shown little appetite for those conversations. The frustration is evident in how American officials frame it—not as a negotiation between equals, but as a repeated plea for Beijing to simply show up and talk.

What emerges from these parallel tracks of diplomacy is a picture of two powers trying to manage a relationship that has become genuinely difficult to manage. The U.S. is not asking China to change its fundamental interests or ambitions. It is asking for restraint in how those interests are pursued, for communication when tensions spike, and for willingness to discuss the weapons that could make any miscalculation catastrophic. Whether Beijing is willing to meet those requests remains unclear. China has not yet confirmed the Biden-Xi meeting, and a senior Biden administration official acknowledged this week that important details have yet to be worked out. The talks in Beijing on Friday may have been candid, but candor is not the same as agreement.
