Taiwan scrambles fighters over fourth Chinese incursion in five days
Washington has sent two envoys to Taipei in as many months, infuriating Beijing, which considers the self-ruled island as part of its territory, to be absorbed into the mainland -- by force if necessary.
Taipei's defence ministry said that Taiwan maintains "the right to self-defence and counter attack" in the wake of the "frequent harassments and threats."
"Our primary principle is not to provoke, not to heighten conflicts, trigger incidents or cause misfire," defence minister Yen De-fa told reporters.
"But we are not afraid of a war and we must maintain our necessary right to self-defence and counter attack."
Beijing has ramped up diplomatic, economic and military pressure on Taiwan since the 2016 election of President Tsai Ing-wen, who rejects its view that the island is part of "one China".
Washington's increased outreach to Taiwan under President Donald Trump has become yet another flashpoint with China as the countries clash over a range of issues of trade and security issues, as well as the coronavirus pandemic.
