People's Financial News, October 13, Lu Daliang, spokesperson of the General Administration of Customs and director of the Statistical Analysis Department, said at a press conference on October 13 that relevant departments have responded many times to the issue of port fees for ships. The US measures are typical unilateralism and protectionism, and have obvious discriminatory overtones. China's countermeasures are necessary passive defensive actions. They are not only measures that have to be taken to safeguard the legitimate rights and interests of China's industries and enterprises, but also necessary measures to maintain a level playing field in the international shipping and shipbuilding markets. It is hoped that the United States can face up to its own mistakes, move in the opposite direction with China, and return to the right track of dialogue and consultation.
