US House China Committee Chair John Moolenaar Urges Trump to Confront Xi on Taiwan, Iran, and Technology

On Friday, September 18, 2026, John Moolenaar, the Republican chair of the US House Select Committee on China, urged President Donald Trump to take a tough line in his upcoming summit with Chinese President Xi Jinping. In a letter, Moolenaar warned against concessions, called for tighter technology restrictions, and demanded consequences for China's alleged support for Iran. He also stressed the need to maintain US support for Taiwan and pressure Beijing over detained US citizens. The letter reflects concerns among China hawks that Trump might soften his stance. Trump has previously described US arms sales to Taiwan as a negotiating chip.
