TAIPEI (Reuters) - Taiwan will keep close contact and deepen its ties with the United States, the Presidential Office said Friday, in reaction to U.S. President Donald Trump’s phone call with China’s leader in which he agreed to honor the “one China” policy.  “Taiwan and the U.S. both maintain close contact and communication so as to keep a ‘zero accident’ approach (to the relationship),” Presidential Office spokesman Alex Huang said in a statement.  “Maintaining good Taiwan-U.S. and cross-Strait relations (with China) fulfill our national interest and are key for regional peace and stability.”
