State-run Kuwait Petroleum Corporation (KPC) and the Beijing-based Sinopec jointly plan to build a USD 9 billion oil refinery and petrochemical complex in Zhanjiang city in south China's Guangdong Province.
The construction works are due to start next year and complete by 2014, KPC said in June.
The mega project, which includes a 300,000 bpd refinery, ethylene cracker with the capacity of one million ton per year and a retail network in the province, will pave the way for OPEC-member Kuwait to achieve its China-bound crude oil export target of 500,000 bpd.
