Evergreen topic hub, last updated Sep 30, 2026. This page collects Peter’s World’s coverage of tensions between China and Taiwan: daily Chinese military activity tracked by Taiwan’s Ministry of National Defense, U.S.–China diplomacy, arms sales and the political context. Every relevant report we have published is listed newest first.
State of play, September 30, 2026
- Military activity: Taiwan’s Ministry of National Defense said 15 of 21 Chinese military aircraft detected on Sep 30 crossed the Taiwan Strait median line during what it called a “joint combat readiness patrol,” per Taiwan’s Central News Agency. Taiwan News reported 232 aircraft and 312 ships tracked so far in September. Daily counts swing widely: the ministry reported three aircraft on Sep 28.
- Summit diplomacy: President Trump and Xi Jinping ended a three-day summit in Washington on Sep 25 without a public breakthrough, per Reuters. Xinhua said Xi urged the U.S. to oppose “Taiwan independence.”
- Arms sales: a roughly $14 billion U.S. arms package remains on hold. Taiwan’s Defense Minister Wellington Koo said on Sep 29 that existing sales are unchanged and talks continue, per AP via The Hindu. Taipei officials told TaiwanPlus the delay is about timing and specific items; the Chinese side has pressed Washington to stop arms sales.
- South China Sea: USNI News reported Chinese ships blocked a Philippine resupply mission to Second Thomas Shoal on Sep 24. China’s coast guard accused Manila of breaching commitments; Manila disputes that.
How tensions are measured
Taiwan’s Ministry of National Defense publishes a daily report covering the 24 hours to 6 a.m., listing People’s Liberation Army (PLA) aircraft, PLA Navy ships and Chinese “official ships,” and how many aircraft crossed the median line of the Taiwan Strait or entered Taiwan’s air defense identification zone (ADIZ). Taiwan responds with combat air patrols, navy ships and coastal missile systems. The median line is an unofficial centerline. Because counts rise and fall with Chinese exercises and political events, single days say little; the pattern matters. We publish these reports as they are released, and they form the bulk of the list below.
The political and strategic background
Beijing claims Taiwan as part of China and has never renounced the use of force, according to our background report. Taiwan is democratically governed and says it buys arms to defend itself against a possible invasion, per AP. The United States does not formally recognize Taiwan as a country but is bound by U.S. law to help it defend itself, per AP. Our report on China’s ambitions toward Taiwan, which draws on the Institute for the Study of War, says U.S. intelligence assesses that China does not currently plan a full-scale invasion in 2027, and that Beijing is instead intensifying gray-zone coercion. We report that as ISW’s account of the U.S. assessment.
Other recent threads: China protested Taiwan Vice President Hsiao Bi-khim’s visit to Italy and the EU in September, saying Taiwan is an inalienable part of China, while a U.S. State Department spokesperson said Taiwan’s relationships benefit host countries. Reuters and our reporting describe an ongoing purge of senior PLA leaders, including Zhang Youxia and Liu Zhenli, with analysts debating the effect on readiness; the PLA Daily editorial line blamed them for harming the military. Taiwan has also begun flight tests of its first MQ-9B SkyGuardian drone. Taiwan holds nine-in-one local elections on Nov 28, and Trump and Xi are expected to meet twice more this year, at the APEC forum in Shenzhen and the G20 in Miami, per TaiwanPlus.

Frequently asked questions
What is the Taiwan Strait median line?
An informal midpoint in the strait that Chinese and Taiwanese aircraft historically avoided crossing. Taiwan’s ministry counts crossings as a measure of pressure.
Is China about to invade Taiwan?
Our background report, citing ISW, says U.S. intelligence assessed that China does not currently plan a full-scale invasion in 2027 and is relying on gray-zone coercion. Assessments can change.
Does the U.S. recognize Taiwan?
Not formally. Washington maintains a One-China policy and unofficial ties with Taipei, and U.S. law commits it to provide Taiwan with the means to defend itself, per AP.
Why do arms sales matter?
China treats them as interference; Taipei and many U.S. lawmakers see them as essential to deterrence. AP describes the roughly $14 billion package on hold as a record.
