In most countries, 9% GDP growth is a galloping rate. For China, however, this figure marks a 7-year low, and has prompted acute concerns about social stability. The country's leadership has responded with a stimulus plan that will change the world.

Based on the targets of this spending -- roads, railroads, ports, etc. -- I agree with my colleague Chris Barker that this action relights the torch for commodities. Chris pointed to CNOOC (NYSE:CEO) as a way to play the stimulus, and a recent bit of news strengthens that suggestion.

A CNOOC representative today revealed a plan to invest $29 billion in the South China Sea through 2020. This is one of the world's most prospective deepwater basins, and the statement sends a strong signal about China's commitment to investing in oil for the long haul. This is reassuring in a period of plunging crude prices, and jives with some other major oil players showing signs of life upstream.

I've eyed CNOOC's deepwater prospects before, and Petrobras (NYSE:PBR) has bubbled up as a potential partner. Other firms already prospecting the South China Sea include Devon Energy (NYSE:DVN), Anadarko Petroleum (NYSE:APC), and Newfield Exploration (NYSE:NFX). If you're not interested in going all-in on the China offshore oil story with CNOOC, those E&Ps could give you some exposure, while keeping you rooted here at home.

Of course, a host of oilfield servicers stands to benefit as well. Atwood Oceanics (NYSE:ATW), for example, has a future Chinese drilling commitment under its belt, and subsea systems supplier Cameron International (NYSE:CAM) has a growing presence in the country.
