China\'s semiconductor equipment company Prinano (PRINANO) said it has succeeded in making photonic chip wafers without ASML\'s deep ultraviolet lithography tools, using its own nanoimprint lithography technology. The company said it produced 8-inch wafers and could cut manufacturing costs to about one-tenth of conventional methods. The announcement draws attention as export controls restrict China\'s access to advanced lithography equipment, though some analysts urged caution due to undisclosed yield, throughput and mass-production timelines.

Taiwan is reviewing a plan to tighten restrictions on exports of AI chips to all customers in China, potentially extending controls beyond blacklisted firms and criminalising AI server smuggling. The debate centres on how closely Taiwan will align with U.S. export-control standards. Taiwan’s economy ministry said it will strengthen oversight of strategic high-tech products and is consulting the United States on adding advanced chips to controls.
