The United States health secretary has just arrived in Taiwan for a visit that has angered China.
Alex Azar's three-day trip is being hailed as an opportunity to strengthen cooperation in combating COVID-19.

It is the highest-level visit to the island by an American diplomat in more than 40 years.
