China’s Military Operations Around Taiwan: The New Normal in the Taiwan Strait

Beijing’s Blunt Warning to Taipei

On Thursday, May 28, China’s Ministry of National Defense issued an unusually direct statement. Defense spokesperson Jiang Bin declared that Taiwan should not “interfere” in Chinese air force missions around the island, insisting those operations take place “within Chinese airspace” .

“Taiwan is a part of China,” Jiang stated, adding that Taiwan’s armed forces should “refrain from interference and provocation.” The language reflects Beijing’s broader rhetorical posture in 2026, which has hardened since the election of Taiwanese President William Lai Ching-te. China’s annual government work report this year shifted from “opposing Taiwan independence” to “cracking down on Taiwan independence,” signaling a more combative official stance .

Trump-Xi Summit: Strategic Ambiguity Meets a $14 Billion Question

The military maneuvers unfolded against a backdrop of heightened diplomatic uncertainty following the Trump-Xi summit in Beijing on May 13–15.

President Trump largely adhered to Washington’s traditional posture of strategic ambiguity on Taiwan, but he departed from his predecessor Joe Biden’s practice of proactively emphasizing U.S. interest in Taiwan Strait stability . Trump’s post-summit comments focused instead on the status of a proposed $14 billion arms package for Taiwan, which includes missiles and air defense systems and has been stalled for months. He stated that he had not decided whether to proceed with the sale and described it as “a very good negotiating chip” .

Trump also acknowledged during a press interview that he discussed arms sales “in great detail” with Xi Jinping, and appeared to dismiss the Six Assurances — a 1982 U.S. policy pledge that Washington would not consult Beijing on arms sales to Taiwan — by remarking, “1982 is a long way… a big far distance away” .

The implications are significant. Taiwan’s supporters on Capitol Hill had already urged Trump to move forward with the delayed package before the summit, and U.S. senators have since continued to press for expedited approval . For Taipei, the uncertainty goes to the heart of its defense planning. Taiwan’s government responded firmly, stating that U.S. arms supplies are “based on US law” under the Taiwan Relations Act and serve as a shared deterrent to regional threats .

Taiwan’s Reassurance and Washington’s Mixed Signals

Taiwanese officials have publicly emphasized that U.S. policy remains unchanged in substance, even if the Trump administration’s tone has shifted. In practical terms, however, the largest weapons sale ever authorized for Taiwan — an $11 billion package approved in December 2025 — has yet to deliver, and the proposed $14 billion follow-on sale remains in limbo .

Analysts note that the real test for U.S.-Taiwan defense ties will come when Trump makes a final decision on the arms package. That choice will reveal whether Washington’s strategic ambiguity still includes meaningful military support for Taipei — and whether Beijing is prepared to impose costs for any deviation from its demands .

Why the Median Line Matters

For decades, the median line in the Taiwan Strait functioned as a practical, if legally informal, boundary. Neither side formally recognized it in a treaty, but both militaries observed it as a deconfliction measure.

That changed in 2022. Beijing now claims sovereignty over all airspace and waters around Taiwan and has publicly renounced the line. PLA aircraft and vessels cross it as a matter of routine policy rather than exceptional signaling . Friday’s report — 10 out of 10 aircraft crossing — captures the new operational reality. The median line, as a meaningful constraint, no longer exists for China’s military planners.
