Taiwan's largest opposition party, the Kuomintang (KMT), is showing signs of an internal power struggle, which is being closely watched by both China and the U.S. Sources indicate the opposition party has 'two centers of gravity' and its leader, Chairwoman Cheng Li-wun, is drawing criticism. These tensions are emerging weeks ahead of crucial local elections that will set the stage for next year's presidential campaign, according to Nikkei Asia.
