Taiwan opens Arizona mission amid US chip investment

Taiwan's Foreign Minister Lin Chia-lung inaugurated a new de facto consulate in Phoenix, Arizona, on October 5, 2026, during a three-day visit to the U.S. The opening of the Taipei Economic and Cultural Office signifies Taiwan's effort to expand its reach and strengthen economic and trade partnerships, particularly in light of significant semiconductor investment in the state.

Taiwanese chipmaker TSMC is undertaking a substantial $265 billion investment in Arizona for semiconductor manufacturing. Taiwan's foreign ministry described the new Phoenix office as a "milestone in Taiwan-US economic and trade partnership," emphasizing its commitment to linking diplomacy, trade, economics, and industry to foster a mutually beneficial relationship with the United States.

The U.S. remains Taiwan's most crucial international partner and arms supplier, despite the absence of formal diplomatic ties. However, U.S. President Donald Trump has placed a new arms sales package for Taiwan on hold, viewing it as a negotiating chip. Trump and Chinese President Xi Jinping met in Washington last month, with Trump stating that Xi understood his position on Taiwan. China has consistently demanded an end to U.S. arms sales to Taiwan.
