Former Taiwan and Singapore leaders make historic visits to China.

Former Taiwanese President Ma Ying-jeou has become the first sitting or former Taiwanese leader to visit mainland China since the Communist revolution in 1949. The visit has been criticised by Taiwan's ruling Democratic Progressive Party (DPP) of Ma's successor, Tsai Ing-wen. Ma's office said he was met at Shanghai's Pudong International Airport on Monday by officials who included Chen Yuanfeng, deputy head of China's Taiwan Affairs Office. Ma made the trip at a time of heightened tensions between Beijing and Taipei as China keeps up military and political pressure on Taiwan to try to get the democratic island to accept Chinese sovereignty.
