Taiwan’s joint intelligence, surveillance and reconnaissance system has played a major role in monitoring PLA moves against the island in recent weeks, Taiwan’s military said on Wednesday as it stressed that it remained up-to-date on the mainland’s manoeuvres. A Taiwanese defence ministry official said the island would continue to use the system as part of early-warning efforts against a potential attack from mainland China. “Taiwan’s joint intelligence … system is closely monitoring People’s Liberation Army activities around Taiwan for indicators and warnings,” Major General Chang Tsung-tsai from the ministry’s Office of Deputy Chief of the General Staff for Intelligence said in Taipei. The joint intelligence system is designed to show real-time conditions on the ground, in the air, at sea, in space and in cyberspace, and the island shares information gathered through it with the United States and its allies. Chang said that with the system the island’s military had precise information about missiles fired during PLA war games earlier this month. The PLA staged 10 days of large-scale live-fire exercises from August 4 in seven zones encircling the island in retaliation for an announced, but high-profile v isit to Taiwan by US House Speaker Nancy Pelosi. Beijing regarded the visit by Pelosi – second in line to the US presidency and the highest ranking official to travel to Taiwan in 25 years – as a deliberate “provocation” and violation of its sovereignty and territorial integrity. In addition to sending warplanes and drones to harass Taiwan, the PLA lobbed ballistic missiles, some of which were fired over the island and landed in what Japan said was its exclusive economic zone – an area that Beijing does not recognise. “We also have sufficient information on the development and commissioning of China’s nuclear ballistic missiles, which we plan to incorporate into our readiness and deployment planning,” he said. Risk of a clash rises after Taiwan fires at mainland drone, analysts say Major General Lin Wen-huang, an operations and planning chief at the ministry, said the military had developed responses for a potential attack from the mainland. “To counter a Chinese blockade, we continue to strengthen operational resilience and capacity to timely conduct anti-blockade escort missions and to deter and complicate the enemy’s operations,” he said. Lin said the war games had given a more concrete picture of the PLA’s likely courses of action and operational progression in an attack on Taiwan. “[Taiwan’s] forces will continue to modify response measures and operational plans based on the threat situations, so that we ready ourselves for defensive operations,” he said. During the war games, the PLA sent warplanes and warships across the median line in the Taiwan Strait, which both sides had long observed as an unofficial demarcation line between the island and the mainland. The effort was seen as an attempt by the mainland to normalise its military operations close to Taiwan . Lin said the military would continue to respond in these cases and “act in accordance with the existing procedures to either issue radio warnings, dispatch air force to address the situation, or use air defence missile systems to track and respond to the threats”. “Our stance is that the closer the incursions are to Taiwan, the stronger our countermeasures will be,” he said. “We will use naval and air forces and coastal weapons to repel PLA forces that enter our 24 nautical mile or 12 nautical mile zones. “When PLA aircraft and ships are in our 12 nautical mile territorial sea and airspace, we will act in accordance with operational orders to exercise the right of self-defence.” Beijing sees Taiwan as its own territory that must be brought back to the mainland’s fold by force, if necessary. Most countries, including the US, do not recognise Taiwan as an independent state. Washington, however, opposes any attempt to take the island by force.
