BEIJING - The Chinese government announced Wednesday that it has approved the establishment of an international cooperative demonstration zone in Northeast China's Jilin province to boost cross-border cooperation in the region.

In a document posted on the central government's official website, the State Council said the zone is expected to expand investment cooperation in northeast Asian regions.

Located in the port city of Hunchun, the demonstration zone will cover 90 square km and include an international industrial cooperation zone, a border trade cooperation zone and economic cooperation zones -- one between China and the Democratic People's Republic of Korea (DPRK) and another between China and Russia, it said.

The demonstration zone will focus on the development of local manufacturing and processing industries, including those for auto parts, agricultural and animal products, seafood, new materials, medicines, textiles and garments, the document said.

The Tumen River in Hunchun straddles the borders of China, Russia and the DPRK. In 1992, China, Russia, the DPRK, the Republic of Korea (ROK) and Mongolia launched a joint development project in the Tumen River area, a move made to strengthen regional cooperation in the area.

The State Council has called for more efforts to boost the construction of Sino-DPRK and Sino-Russia international transit corridors and promote cross-border economic cooperation between China and the two countries.

More supporting policies, including fiscal and taxation support, will be implemented to encourage the development of new energy, new material equipment manufacturing and other projects in the demonstration zone, according to the State Council.

The construction of the demonstration zone will also make border regions more open to the outside and strengthen the social and economic development of local areas, the document said.
