Capital investment from China is particularly useful to upgrade quality of infrastructures, speed up development of unconventional natural gas industry, and revive manufacturing sectors in the United States. In retrospect, the American infrastructural sector has a history of tapping foreign funds to facilitate its development. In the late 19th century, for example, over 20 percent of American railroad construction was financed by foreigners. Moreover, opening-up of the U.S. shale gas industry for foreign investment will accelerate the U.S. energy independence and also help the American firms use their advanced technology to exploit the huge Chinese shale gas reserves with the inclusion of reciprocal clauses. Recently there are a few encouraging investments in this area from China, for example, during 2010-2011 China’s Cnooc corp. bought stakes in Chesapeake Energy’s shale fields in Texas, Colorado and Wyoming; and in 2012 China’s Sinopec corp. set up joint venture with Devon Energy corp. to drill oil and gas in the U.S. Midwest. In every respect, it is uneconomical to turn away investments from China and investment protectionism will only impede the U.S. economy. In Europe, the situation is even worse, where the ailing banking system is contracting and widespread fears halt local companies from investing. But the economy won’t resume normal growth to alleviate unduly high unemployment unless bank lending to small and medium enterprises resurge and investments in industries start growing.
