US arms sales to Taiwan are turning the island into a powder keg, says Liu Pengyu. The move is a violation of the "one China" principle, he says.

The U.S. has also ordered four MQ-9B UAVs for Taiwan for $250 million, he adds. Liu: The move sends the "wrong signal" to the forces advocating "Taiwan independence" for the first time in 50 years. He was speaking to TASS on behalf of the Chinese Embassy in Washington.
