NEW YORK - Moving factories from China to Mexico is one of the few hot topics in an otherwise listless market, US investment bankers say. As American hostility to China rises, US corporations scramble to assure the public as well as inquisitive congressional committees that they are moving operations out of the Middle Kingdom to friendlier venues. It’s all a pantomime for political consumption. US imports from Mexico, Vietnam, India and other “friend-shoring” venues depend on imports of Chinese components, according to an Asia Times study of international trade data. China’s exports to non-Japan Asia and Latin America are booming, and Chinese companies are investing billions of dollars in Mexico. The charade permits American politicians to flaunt success in decoupling from China, and gives corporate leaders a chance to display their patriotism – while America’s indirect dependence on China’s industrial power increases.
