The snow had delayed or canceled 122 flights from and to Urumqi, capital of the region, leaving more than 4,000 passengers stranded at the Urumqi airport, an airport official said late Monday.
Food and water had been provided to the stranded passengers. Flights began to resume since 7 p.m. Monday.
Nine avalanches occurred on the national highway section in Ili Kazak Autonomous Prefecture, leaving one dead and two injured.
More than 1,000 passengers in 150-odd vehicles had been stranded on the highway in the wake of the avalanches. Traffic began to resume after more than 100 rescuers were sent to the scene.
The snow had affected more than 1.6 million people, killing four of them and injuring 623 others, said an official of the regional civil affairs department.
The direct economic lost was estimated at 345.3 million yuan ( 50.8 million U.S. dollars).
