With tensions escalating in the Taiwan Straits, the Chinese mainland authorities announced Tuesday economic punishment on Taiwan secessionists, fuelling speculation as to where trade between the Chinese mainland and the island of Taiwan will be headed. The Democratic Progressive Party DPP is pursuing secession with provocative acts and colluding with foreign forces, which is the root cause of the current serious and complicated situation in the Taiwan Straits. With the pandering of the DPP, US House Speaker Nancy Pelosi landed in Taiwan on Tuesday night, in spite of stern warnings from China. By using the island as a political toy, she deliberately created the crisis with malicious provocation, without regard for the dilemmas that the island will face or the interests of the people of Taiwan at all. The beneficiaries of cross-Straits' economic ties should be the compatriots on both sides of the Strait, instead of Taiwan secessionists who want to undermine peace and stability across the Strait and split Taiwan from China with the help of external forces. China's willingness to expand and deepen cross-Straits economic and trade cooperation hasn't changed. Cross-Straits' economic cooperation will continue and deepen on the basis of the interests of grand cause of national reunification, while also avoiding becoming the cash cow supporting Taiwan secessionist forces with ulterior motives. Now as the DPP authorities are making more provocative moves to seek secession by relying on external interference forces, it is important to target and punish businesses that support Taiwan secessionist forces while ensuring that the dividends of cross-Straits trade relations will promote the people-to-people exchanges and national reunification. The Taiwan Affairs Office of the State Council announced Wednesday that Chinese mainland authorities will take punitive measures against the International Cooperation and Development Fund ICDF and the Taiwan Foundation for Democracy TFD, two organizations that have close ties with diehard secessionists. Organisations, enterprises, individuals and businesses that provide financial support or services for them will be punished. On Wednesday, customs of the Chinese mainland announced that they would suspend entry of citrus fruits and some frozen fish from the Taiwan island. Taiwan's farming and fishing is mostly concentrated in the southern part of the island, a region that is traditionally the DPP's main voting bloc. The DPP will have to deal with a crisis when its voting base is in trouble. The Taiwan island's trade surplus against the mainland last year was over $170 billion, with its trade surplus against the mainland reaching $250 billion last year. The cross-Straits' economic achievements are the result of the hard work of the people on both sides. The momentum of cooperation must not be sabotaged by the secessionist forces of Taiwan. Some countries may want to use the so-called trade improvement issue with Taiwan to boost their relations with the island. Do they care about the interests of Taiwan people if they offer island arms, pork and beef containing ractopamine and nuclear contaminated food? The DPP has no regard for the benefits of the people of Taiwan and only cares about the political gain of selling the island to external forces. The people of Taiwan should realize that supporting Taiwanese secessionist forces is a dead end for the island. It is important to punish those who maliciously use the island to provoke China's core interests to deter the trend from spreading further. The Taiwan government can't use the money it earns from trade with the mainland to buy US arms.
