Taiwan President Tsai Ing-wen said Sunday that she has no plans to have phone talks with new Prime Minister Yoshihide Suga after signals emerged that he might be open to the first direct talks with Taipei in decades.

Beijing warned Tokyo a day earlier against closer ties with Taipei after former Prime Minister Yoshiro Mori mentioned the possibility to Tsai during a recent meeting.

Chinese Foreign Ministry spokesman Wang Wenbin said in a statement that Beiijng had spoken with Tokyo and that such a call “will never happen.”
