A video feed of a Taiwanese minister was cut during U.S. President Joe Biden's Summit for Democracy last week after a map in her slide presentation showed Taiwan in a different color to China, which claims the island as its own.

Sources familiar with the matter said that Friday's slide show by Taiwanese Digital Minister Audrey Tang caused consternation among U.S. officials after the map appeared in her video feed for about a minute.

The sources, who did not want to be identified due to the sensitivity of the matter, said the video feed showing Tang was cut during an ongoing panel discussion and replaced with audio only — at the behest of the White House.
