GYIRONG, Tibet, May 8  -- Traffic resumed along the Gyirong Pass highway on Friday, 13 days after the devastating earthquake in Nepal triggered multiple landslides that blocked the China-Nepal border road.

Police said the highway in southwest Tibet Autonomous Region, reopened at about 4 p.m., after debris from all 28 landslides was cleared.

The highway is vital for rescue efforts and reconstruction work, as well as China-Nepal border trade, said Hu Hong, county head of Gyirong Town.

China's border trade with Nepal was almost obliterated after Zham and Gyirong, two towns on the Tibet-Nepal border, were left inaccessible after the earthquake and ensuing tremors. Access into the Zham Pass was restored on May 1.
