On Sunday and Monday, the Chinese People's Liberation Army PLA sent warplanes near the island of Taiwan. On Sunday, 39 aircraft flew, the largest daily number this year. The DPP authority of the Democratic Progressive Party appeared very nervous and upset. It has become normal for PLA warplanes to fly around Taiwan and approach the island for patrols. A sword of Damocles is hung over the head of Taiwan secessionists, and at the same time it concretizes and materializes the warning and deterrence of the Chinese mainland. There is no essential difference between PLA warplanes flying over Taiwan and US military warplanes over Hawaii. Taiwan is part of China's territory. There is never been a concept of Taiwan airspace in the world, but only China airspace. The DPP authority does not have a right to designate the so-called air defense identification zone. The Taiwan secessionists and the forces supporting them have fabricated the rhetoric of Taiwan airspace and intrusion, which is nothing more than an attempt to hide their desire to undermine peace. The PLA has increased the activities of its warplanes flying around Taiwan since 2020. This is not only a solemn declaration of China's sovereignty, but it is also a severe warning to Taiwan secessionist forces. Over the past two years, the DPP authority and Taiwan secessionist forces have made more moves towards independence, and the plot of external forces to exploit Taiwan to contain Chinese mainland has become more explicit. The US has been playing the Taiwan card more frequently from the Trump administration to the Biden administration, playing edge balls and conducting salami slicing tactics on the one-China principle. It has encouraged the arrogance of Taiwan secessionist forces, provoking the Chinese mainland. In 2021, US large spy planes carried out about 1,200 aerial close-in reconnaissance sorties on China. US aircraft carriers and warships have many times intruded China's maritime space. One day before Taiwan was panicked by the PLA's 39 warplanes flying toward it, two US carrier groups and the Japan Maritime Self Defense Force conducted a military drill in waters near Taiwan island. Who is the outsider coming here to stir up trouble? Who is creating tension in the region? The answer is obvious. The effect of PLA warplanes flying around Taiwan island is obvious. If there is no strong anti-secessionist military deterrence from the PLA, would the DPP and Taiwan secessionist forces be more arrogant and radical? Will they go further in the secessionist direction? They don't want to promote the de jure independence of the Taiwan island, not because they grew a conscience, but because they dare not. They are fully aware that the PLA will definitely take decisive measures, so they do not have the nerve to do whatever they want. The pressure from the PLA has caused some people on the island to think more deeply about the future of the island, and to make a forceful critique of the separatist behavior of the DPP authority. According to Taiwan's statistics, the PLA warplanes conducted nearly a thousand patrols around the Taiwan island in 2021. The figure has reached 109 in less than a month this year. The total for 2022 will only be more than last year. The fighter group could turn to a specific mission once a special scenario occurs, as there were 39 warplanes that flew around Taiwan last weekend, 34 of which were fighter jets, including J -- 16 s and J -- 10 s. On Monday, the PLA's J- 16 D, which entered service recently, showed up for the first time in a mission near Taiwan. The message is self-evident. In the future, the mainland will continue to strengthen capacity building and resource accumulation for unification with more practical actions, according to analysts. Warships will also continue regular patrols in addition to the PLA warplanes. PLA warplanes will not only fly around the island, but they will also fly over the middle line at any time, according to the situation, and will sooner or later fly over the island. If the secessionists take a step forward, we will certainly increase the military and comprehensive pressure on them. The DPP authority has claimed that the PLA sent more warplanes for regular patrols near Taiwan island than the defense ministry and the Taiwan Affairs Office of the State Council. The flight routes have been like a noose tightening around the neck of the Taiwan secessionists, making them feel breathless. If these stubborn secessionists continue to challenge the bottom line of the one-China principle, the noose will become tighter.
