BEIJING -- China and the Democratic People's Republic of Korea said on Friday that they would push forward in developing economic zones.

Jang is in China for the third meeting of the joint steering committee for developing and managing the Rason Economic and Trade Zone and the Hwanggumphyong and Wihwa Islands Economic Zone.

Wen said both sides should give priority in developing and managing the zones as well as implement the consensus reached by the joint steering committee.

The premier said the two governments should strengthen the leadership and planning of the cooperation on the zones, improving laws and regulations; encourage relevant regions for active participation with close coordination; and let the market play its role creating favorable conditions for land and tax.

He called on the committee to encourage businesses to invest in the zones and help enterprises solve their problems, and improve customs and quality inspection services to help with bilateral cooperation.

Jang said the development of the zones had entered a substantial phase and DPRK was willing to work with China to accelerate progress.
