China claims democratically governed Taiwan as its own territory and in the past two years has stepped up military and diplomatic pressure to assert its sovereignty claim, fuelling anger in Taipei and concern in Washington, Reuters reported.
By "encouraging 'Taiwan independence' forces" the United States "not only puts Taiwan into an extremely dangerous situation, but also exposes the United States to an unbearable price", Wang said.
Taiwan has emerged as a key factor in strained relations between China and the United States, the island's most important international backer and arms supplier despite the absence of formal diplomatic ties.
Taiwan says it is an independent country and vows to defend its freedom and democracy. China regularly describes the island as the most sensitive issue in its ties with the United States.
"Taiwan has no other way forward other than reunification with the mainland," said Wang.
