The Paris-based Organization for Economic Cooperation and Development (OECD) is mulling over China's entry to the market economy club.

Angel Gurria, OECD secretary-general, said it has already "expressed interest" in a membership offer to China.

"We (China and the OECD) know each other well and we have already conducted closer cooperation in many fields," Gurria said yesterday at the China Development Forum in Beijing.
