China summons Kaye Lee, the U.S. deputy chief of mission in Beijing, to protest Washington's announcement that it is selling two warships to Taiwan as part of a $1.83 billion arms deal. U.S. state department spokesman John Kirby says the sale is consistent with the 1979 Taiwan Relations Act while Chinese Vice-Foreign Minister Zheng Zequang threatens to impose sanctions on U.S. firms because the proposed sale "severely damaged China's sovereignty and security interests."
