Why does Kunming Customs manage the customs of the whole province?

The reason why Kunming Customs manages the customs of the whole province is because Kunming is the capital of Yunnan Province and its geographical position is important. Kunming Customs is located in Kunming, the gateway city of China that is open to South Asia and Southeast Asia. Its jurisdiction covers the whole province of Yunnan Province, with a border of 4,060 kilometers, bordering Myanmar, Laos and Vietnam. There are 25 ports in the customs area, including highway port 18, air port 4, water port 2 and railway port 1. 1951August 15, Kunming customs and Tengchong customs merged into Kunming customs, becoming the only leading agency of customs in the province. 1980, Kunming Customs was renamed Kunming Customs, which was one of the first nine upgraded departments in China.
