Construction teams in Tibet have sped up repairing a highway section that suffered a severe mountain landslide last year on the Sino-Nepal Highway.

The repairing has been going smoothly so far and the major part of the project will have been finished by the end of June, said Cao Zhixing, a leading official with the project.

The repairing is sped up to ensure smooth transportation on the highway during the rainy season, which is usually set in from June to August.

On July 25 last year, a roadbed of 110 meters long on the highway was damaged by a landslide from the Zhameila Moutain on the border of China and Nepal.

Transportation on the highway had to be suspended for more than one month and supplies for production and living to the 5,000 households in the nearby Zhangmu Town along the mountain was cut off.

From January this year, the second detachment of the Armed Police Force of Tibet has been undertaking the job to mend the section.

As located to the south of the Himalayas, the damaged section is in an area that sees an abundant rainfall with precipitation exceeding 3,000 mm each year and the mountains it cuts through are more likely to break out landslides.

The Sino-Nepal Highway is an important route for the exchanges between China and Nepal and other south Asian countries. It is also the only way to the Zhangmu Port, Tibet's biggest country-level land trading port.

The border trade volume amounted to more than 100 million U.S. dollars in recent years, making up 70 percent of Tibet's total of both import and export.
