A chartered flight operated by China Eastern Airlines took off from Kunming, the capital of southwest China's Yunnan Province, Sunday afternoon, carrying about 7.3 tonnes of relief goods to earthquake-hit Myanmar.

The relief goods were sourced and collected in Yunnan, which include clothes, medicines, instant noodles, tents and other daily necessities.

After the 7.9-magnitude earthquake struck Myanmar on Friday, the Kunming Customs started the coordination mechanism of emergency customs clearance, and arranged customs officers to be on duty 24 hours a day to ensure the rapid inspection and release of passing vehicles.

According to data of the checkpoint in Ruili, from Friday to Saturday, there were more than 15,000 people and more than 1,240 vehicles passing through.

"There is no obvious fluctuation on the passage, and the checkpoint is running smoothly and orderly," said He Qigang, an officer with the Ruili Customs.
