BEIJING - Chinese Commerce Minister Chen Deming said Monday that China will make more vigorous efforts to promote comprehensive and in-depth development of Sino-foreign investment cooperation.

While fulfilling commitments such as cutting tariffs that China made when joining the WTO, the nation is advancing a series of new opening measures, Chen told a forum attended by member representatives of the China Association of Enterprises with Foreign Investment.

China will further promote industrial upgrading and restructuring, develop new channels for institutional and technological innovations, make its service sectors more open to foreign markets and optimize foreign investment environment in its 12th Five-Year Plan period (2011-2015), Chen said.

About 104 service sectors including finance, telecommunications and construction industries are currently open to foreign investment, compared with the average level of 108 in developed economies, said Chen, adding that many new opening measures were underway.

On safeguarding intellectual property rights (IPR), Chen noted that the government was making unremitting efforts in its battle against IPR infringements while strengthening lawmaking.

He reiterated that all companies that are registered in China according to Chinese laws are the country's enterprises, and enjoy national treatment and their products are "made in China."
