China should abandon threats against Taiwan, US diplomat says

TAIPEI, April 12 - The top U.S. diplomat in Taiwan said China should abandon its threats and military pressure against Taiwan and talk to the island's leaders as that would avoid misunderstandings and stabilise relations.    Raymond Greene, the de facto ambassador as head of the American Institute in Taiwan, which handles relations in the absence of formal diplomatic ties, said the consistent U.S. policy has been to support exchanges across the Taiwan Strait.
