Though Washington severed diplomatic relations with Taipei in 1979 to recognize Beijing as China's sole official representative, the United States remains Taiwan's most powerful ally and its top arms supplier.
Tai discussed the issue on Monday with drugmakers Pfizer and AstraZeneca PLC, noting her interest in a solution that gave developing countries a role in addressing critical gaps in vaccine production and distribution.
Tai said in a statement that Myanmar security forces' killing of peaceful protesters, students, workers and labor leaders and children "has shocked the conscience of the international community."
"These actions are a direct assault on the country's transition to democracy and the efforts of the Burmese people to achieve a peaceful and prosperous future," said Tai, who was sworn into office on March 18.
The European Commission said in response to the move that it "regrets that the United States has chosen to add further EU products to its retaliation list in the WTO Airbus case on aircraft subsidies."
