China issues warning over US-Taiwan meeting, threatens retaliation.

China has warned of "resolute countermeasures" if Speaker Kevin McCarthy meets with Taiwanese President Tsai Ing-wen during her transit visit to the US. China's Taiwan Affairs Office spokesperson Zhu Fenglian said that the US should "refrain from arranging Tsai Ing-wen's transit visits and even contact with American officials." Tsai plans to pass through New York and Los Angeles either before or after a 10-day trip to Guatemala and Belize this week and is widely expected to meet with McCarthy while in California.
