A new experimental area for development and opening-up at the border of North China's Inner Mongolia Autonomous Region has been approved, said a local official on Monday.

Erenhot, an inland port city which borders Mongolia, was approved as one of China's 13 border cities for opening-up in 1992 and is now among the few inland ports with a cargo throughput of more than 10 million tons per year.

In 2013, the cargo throughput via the railway and highway ports of Erenhot reached 13 million tons with a trade volume of $3.65 billion.

The experimental area will enjoy preferential policies in financing, land, investment and industry to attract capital, talent, and new technologies.
