Daily Intelligence Briefing: China/Taiwan Monitor
Executive Summary
US-China relations show increasing strain as reports emerge of China sharing intelligence on US troops with Iran, potentially affecting preparations for President Trump's May visit to Beijing. A bipartisan US Senate delegation arrived in Taipei to push Taiwan's defense spending amid delays on HIMARS procurement, while KMT Chairwoman Cheng Li-wun prepares for a high-profile visit to China expected to include a meeting with Xi Jinping. Taiwan's legislature continues to block special defense budgets, complicating US arms deliveries. China's COSCO vessels successfully transited the Strait of Hormuz after initial difficulties, suggesting calibrated coordination with Iran even as Beijing exports fuel to energy-stressed Southeast Asian partners.

Analysis
Cross-strait dynamics are intensifying on multiple fronts. Taiwan's domestic politics remain a key friction point, with the KMT simultaneously blocking defense appropriations in the legislature while the party chair prepares for a symbolic meeting with Xi in Beijing. The optics of a KMT-Xi summit ahead of Trump's planned May visit to China suggest Beijing aims to shape the narrative around Taiwan's political divisions. Meanwhile, US engagement remains robust through the Senate CODEL visit, AIT Director Greene's public comments supporting Taiwan democracy, and flexibility on HIMARS payment timelines. Chinese "kill switches" found in US solar infrastructure and cellular equipment, plus continued UNCLOS airspace violations, indicate persistent gray-zone competition. The China-Iran intelligence-sharing angle adds a new dimension to US-China-Israel-Iran dynamics and may complicate summit preparations.
What to Watch: KMT-Xi meeting details and timing; Taiwan legislature's defense budget resolution; Trump administration's response to reports of China-Iran intel cooperation; COSCO and broader Chinese commercial shipping movements in Persian Gulf.

Exclusive: China is sharing intel on U.S. troops and equipment with Iran, source says https://t.co/nn7Fu9RiiE "When I reached out to the White House, explaining that a source had told me that China was sharing intelligence on U.S. military personnel in Iran and that this was a factor in Trump's delayed visit with Xi, spokeswoman Olivia Wales did not contract or challenge the information. Instead, she told me by email, "Nothing provided to Iran by any other country is affecting our operational success." → tweet link
