SHENYANG -- A new bridge will link China and the Democratic Republic of Korea (DPRK) by 2014 and greatly boost exchange and trade between the two countries, officials said Monday.

A new border trade complex, complete with customs services, border control and quarantine services, as well as office buildings, hotels and markets will also be operational by 2014, according to Shi Guang, mayor of Dandong city, where the bridge is located.

The whole complex will cover 38 hectares and cost two billion yuan ($325.8 million) to build, Shi said.

The new bridge is 10 kilometers down the Yalu River from the old bridge, which was built in 1937 and has been sole major passage on the China-DPRK border.

The two governments agreed to build the new bridge in early 2010. It will have four lanes and a span of about three kilometers.

The new facilities will be able to handle as many as 20,000 vehicles and 50,000 people a day and Dandong authorities expect that businesses done at the trade complex will account for 60 percent of China-DPRK trade.
