"It's really impressive how fast China acts," a journalist from a Venezuelan media outlet said on Sunday after witnessing heavy machinery working continuously on rescue and recovery efforts at mudslide-hit Gyirong Port in southwest China's Xizang Autonomous Region. 

"I took a four-and-a-half-hour flight from Beijing to Lhasa, followed by more than 10 hours on the road to reach the disaster-hit area," he said, underscoring just how difficult it is to reach the remote site.

The mudslide, triggered by a high-altitude glacier collapse in Nepal on August 26, left 43 people dead and 519 others missing in Xizang as of Sunday.
