TOKYO (AFX-ASIA) - Finance Minister Masajuro Shiokawa said the ministry will be forced to take action in the foreign exchange market if movements are rapid. "Basically, currency levels should be determined by market forces but wild fluctuations is troublesome," Shiokawa told a parliamentary committee. "If it moves rapidly, we will have to take some action. We have a great interest in the speed of forex movements," he said. "I think major world currencies are in a kind of correction, with the dollar, yen, euro and pound interlinked," he said. "One of the main reasons for the global forex fluctuations is the real US economy is not sufficient to prop up its policy of maintaining a strong dollar." Shiokawa also noted concerns over the Chinese yuan, which some fear is undervalued, increasing China's competitiveness relative to regional rivals. "The US and Southeast Asian countries are interested in the value of the yuan. However, we should not ask partners to coordinate market intervention to cope with the issue of the yuan. The issue should be resolved naturally." em/tb/jv
