TAIPEI/BEIJING (Reuters) - Taiwan vowed on Tuesday to fight China's "increasingly out of control" behaviour after Taipei lost another ally to Beijing when El Salvador became the third country to switch allegiances to China this year.

Taiwan now has formal relations with only 17 countries worldwide, many of them small, less developed nations in Central America and the Pacific, including Belize and Nauru.
