China has stepped up military activities near democratically governed Taiwan since August, when it conducted blockade drills around the island following a visit to Taipei by U.S. House Speaker Nancy Pelosi.The key to peace is to reverse the mindset of handling problems with force," Chiu said, adding Beijing should resolve disagreements with Taipei via "a constructive dialogue without preconditions."China has repeatedly rebuffed offers for talks on the basis of equality with mutual respect by Taiwan President Tsai Ing-wen, who Beijing views as a separatist.Earlier this month, President Xi Jinping said in a speech at the opening of a the Communist Party Congress in Beijing that it is up to the Chinese people to resolve the Taiwan issue and that China will never renounce the use of force over Taiwan.Taipei says only the island's 23 million people can decide their future, and that as Taiwan has never been ruled by the People's Republic of China its sovereignty claims are void."
