Taiwan is pushing for closer economic ties with the US, using a visit by Michigan Governor Gretchen Whitmer to press for a tax treaty and drone industry partnerships — good news for Taiwanese and US businesses investing in each other's markets.

• President Lai Ching-te wants the US and Taiwan to sign an agreement to avoid double taxation, so companies on both sides are not taxed twice on the same income.
• Taiwan is building up its drone industry and wants US partners to help make supply chains stronger and more secure.
• Michigan's car industry and Taiwan's chip and electronics makers fit together well, and more Taiwanese companies are setting up in the state.
• Taiwan became the fourth-largest US trading partner last year, and the US is Taiwan's biggest export market and top destination for overseas investment.
• Whitmer is on her third Taiwan trip in three years, and Taichung signed a sister-city deal with Michigan's Oakland County during the visit.

Outlook: Expect more Taiwanese investment in Michigan's auto electronics and chip design sector, while the double-taxation treaty still depends on action in Washington.
