China's memory semiconductor industry is entering a new phase of expansion as leading domestic players ramp up investments in both NAND flash and DRAM technologies, amid an AI-driven global memory boom and tightening supply conditions.

Among the 19 Taiwan-listed semiconductor materials companies tracked by Digitimes, 10 (53%) grew month-on-month in April, 12 (63%) posted positive year-on-year growth, and 14 (74%) are ahead on a cumulative January–April basis. On the surface, those are reasonable numbers — but the distribution underneath tells a more complicated story.

On May 14, Xi Jinping opened his summit with Donald Trump in Beijing by invoking the Thucydides Trap — the idea that a rising power and an established hegemon are structurally destined for conflict. Then he turned to Taiwan. If not handled properly, he warned, the two countries face clashes and even conflicts.

As the US and China continue to clash over geopolitics and critical materials supply, industry sources say China's restrictions on indium phosphide (InP) substrates for optical communications remain unchanged and are widely seen as part of Beijing's effort to counter US-led AI development.

TSMC's decision to sell down its stake in Vanguard International Semiconductor (VIS) is the second significant portfolio move the company has made in as many weeks — and together, the two transactions sketch the outline of a deliberate capital reallocation strategy centered on AI.

Biwin Storage Technology recently resubmitted its listing application to the Hong Kong Stock Exchange again, with Huatai Financial Holdings acting as the sole sponsor. The Chinese memory module maker has seen a rebound in profit as demand for memory continues to rise.

Delta Electronics Chairman Ping Cheng has warned that companies failing to meet RE100 targets risk losing orders as global customers intensify demands for renewable energy compliance. His comments highlight mounting concern across Taiwan's technology sector that insufficient green power supply could become the next major constraint on the island's semiconductor and electronics industries.

US President Donald Trump's meeting with Chinese President Xi Jinping in Beijing this week has put Nvidia's stalled H200 sales in China back in focus, as Washington's export approvals have yet to translate into revenue for the AI chipmaker.

After the early pull-forward effect from customers began to fade, Taiwan's panel makers have started to show signs of slower operating momentum. Weaker demand for consumer electronics dragged down April revenue at AUO, Innolux, HannStar, and Giantplus.

The US has cleared around 10 Chinese companies to buy Nvidia's H200 artificial intelligence chips, but no deliveries have been made, suggesting that Washington's approval alone may not be enough to revive the company's high-end China business.
