Chinese and Hong Kong investors invested approximately $8.9 billion in US AI funding rounds by mid-September 2026, up from $436 million in 2023, even as Washington and Beijing sought to reduce technology-sector ties. US Wall Street banks also bookran 19 Chinese high-tech equity capital market deals worth $17.2 billion in 2026, while US equities held by Hong Kong and mainland Chinese investors rose 23% over the past year to more than $750 billion. Chinese mutual funds have favored US semiconductor companies including Micron Technology and AMD, highlighting the tension between investment behavior and the broader US-China technology rivalry. President Trump and President Xi Jinping are preparing to meet in Washington around September 24, following Xi's engagement in Beijing during May 2026. AI is expected to be central to the talks, although expectations for a major agreement remain low. Both countries are building independent AI supply chains through measures including US export controls on advanced semiconductors and chipmaking equipment, China's restrictions on critical minerals, and accelerated domestic chip programs. The scale of Chinese and Hong Kong holdings suggests the financial relationship may prove difficult to unwind quickly, even as both sides compete over AI and semiconductor capabilities.
