AKIPRESS.COM - Mongolia's customs has suspended the clearance of coal deliveries at a key border checkpoint into China for miners in the Gobi desert as it works to clear the road of a dangerous traffic jam, Reuters reported.

"It should last until the long queue at the border crossing clears, approximately seven-to-10 days," said a ministry spokesperson about the suspension on Friday.

Coal exports have helped lift the sagging Mongolian economy while foreign investment remains cool.

Mongolia, landlocked between Russia and China, agreed to a $5.5 billion bailout from the International Monetary Fund to relieve debt pressures and stabilise the national currency, the tugrik.

However, less coal is reaching the Chinese market now than the first half of the year, while the Gashuunsukhait-Gants Mod border checkpoint into China is jammed up as customs officials crack down on smuggling.

During the suspension, coal miners will not load new trucks with coal for deliveries, the spokesperson said. He added that operations would resume immediately after the road clears.

Companies will also be held to a quota for deliveries.

The troubles at the border, which began last July, have already slowed growth.

Data from the National Statistics Office shows coal exports grew only 1.7 times to $2.1 billion in the first 11 months of the year compared with more than fourfold growth for the first half of the year.

Coal made up nearly half of the total $4.51 billion earned from mineral exports during January-November this year.
