[vice Foreign Minister Sun Weidong made solemn representations to the ROK Ambassador to China about the ROK leader's erroneous remarks on the Taiwan issue] on 20 April, Vice Foreign Minister Sun Weidong was ordered to make solemn representations to ROK Ambassador Jung Jae-ho about the ROK leader's erroneous remarks on the Taiwan issue. Sun Weidong said that President Yin Xiyue said in an interview a few days ago that the tension in the Taiwan Strait was caused by an attempt to unilaterally change the status quo with strength. South Korea's position is to work with the international community to resolutely oppose the use of strength to change the status quo. The Taiwan issue is not a simple issue between China and Taiwan, but a worldwide issue that transcends the regional level like the North Korean issue. The above remarks are totally unacceptable, and China expresses its serious concern and strong dissatisfaction. Sun Weidong pointed out: there is only one China in the world, and Taiwan is an inalienable part of Chinese territory. The Taiwan issue is purely China's internal affair and the core of China's core interests, and it is the Chinese people's own business to resolve the Taiwan issue, and no force will be allowed to interfere. The fundamental cause of tension in the Taiwan Strait is that "Taiwan independence" elements on the island engage in separatist activities with the support and connivance of foreign forces. The ROK leader said nothing about the one-China principle, but compared the Taiwan issue with the Korean Peninsula issue. Both North and South Korea are sovereign states that have joined the United Nations. It is a well-known fact that the Korean Peninsula issue is completely different from the Taiwan issue in nature, longitude and latitude, and is not comparable at all. We urge the ROK to earnestly abide by the spirit of the joint communique on the establishment of diplomatic relations between China and South Korea, abide by the one-China principle, and be cautious in its words and deeds on the Taiwan issue. Jung Zaihao said that the ROK has always respected the one-China principle, and this position has not changed.
