WASHINGTON, Dec 12 (Reuters) - 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 told Reuters 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.
