US Secretary of Health Alex Azar arrived in Taiwan on Sunday, making him the highest-level US official to visit the island since the US changed diplomatic relations with China in 1979. On Monday, Azar met with Taiwanese President Tsai Ing-wen.
In 2018, President Trump signed the Taiwan Travel Act into law, a bill that allows high-level US officials to visit Taiwan, and vice-versa. This act paved the way for Azar's visit.
Azar's visit is centered around the coronavirus pandemic. The Trump administration has used the pandemic to increase hostilities with China, criticizing Beijing's response and praising Taiwan. "Taiwan has been a model of transparency and cooperation in global health during the Covid-19 pandemic and long before it," Azar said in a statement released ahead of the visit.
