Taiwan's foreign ministry on Sunday pushed back against a joint statement between Beijing and Myanmar that said Taiwan was undisputedly part of China's territory. "The Ministry of Foreign Affairs (MOFA) solemnly protests the joint statement issued by China and Myanmar on January 18, in which Myanmar reaffirmed the so called 'one-China principle' and categorized Taiwan as an inalienable part of the People's Republic of China's territory," MOFA spokeswoman Joanne Ou said in a statement.
