U.S. Energy Information Administration recently said that the U.S. would be the largest oil and natural gas producer in 2013. The U.S. shale gas revolution has changed the global energy landscape. This will not only enhance America's power and influence but also protect the interest of its important allies when the market is unstable. Moreover, it also helps to ease the energy tension with China. The increasing number of suppliers allows China to have diversified sources of natural gas, disperse risks and enhance energy trade negotiation initiative.
