Taiwan has opened a new representative office in Phoenix, a win for Taiwan and for Arizona's chip industry, and a setback for Beijing, which tried to block it.

• Arizona Governor Katie Hobbs attended the opening ceremony even after China's consulate in Los Angeles sent her two letters demanding she oppose the plan.
• The Phoenix office is Taiwan's 14th in the United States and will help Taiwanese companies and the growing Taiwanese community there.
• The main draw is semiconductors: TSMC has pledged another $100 billion to expand north of Phoenix, bringing its total investment in the city to $265 billion, the largest foreign investment in U.S. history.
• China's embassy in Washington said it firmly opposes any official contact between the U.S. and Taiwan, including at the state level.
• The episode shows state governments increasingly making their own calls on Taiwan ties when big factory money is involved.

Outlook: Expect more friction as Beijing presses individual U.S. states, while chip investment keeps pulling Arizona closer to Taiwan.
