Japan is considering joining the U.S. to file a complaint with the World Trade Organization against China. Japan has alleged that China, its largest trading partner, provides Chinese companies preferential taxes in order to gain unfair advantage against foreign firms. The U.S., on the other hand, has already filed a complaint with the WTO against China, alleging subsidies given to some Chinese industries are trade distorting and it makes difficult for foreign firms to compete with them. Washington is arguing that due to these trade distorting subsidies US firms are not being able to match Chinese firms fairly. China and the U.S. held a series of talks to resolve the issue but both countries failed to reach an agreement. The U.S. filed the case last week. In the meanwhile, Japan has said that it is now trying to discover more about the claim that U.S. has filed with the WTO. Though Japan has not made up its mind to file complaint against Chine but its minister for economy, trade and industry, Akira Amari, signaled that they would soon be deciding after examining the findings to whether to join U.S. as a third party. Last week, U.S. trade representative, Susan Schwab, has alleged that China is using tax legislation to encourage export and discriminate against imports. The U.S. while filing complaint with the WTO has called for a level playing field. According to the complaint industries including IT, steel and paper are most affected due to Chinese policies. Japan is heavily dependent on china as a centre for manufacturing.
