Diantan Border Port in Yunnan

Diantan Border Port is located in the northern border region of Houqiao Town (滇滩镇), Tengchong County (腾冲县), Baoshan City (保山市), Yunnan Province (云南省). It borders Myanmar's Kachin State (克钦邦) and is only 10 kilometers from Myanmar's Banwa Special Economic Zone (板瓦特区). The port has been an important military and trade point since the Nanzhao Kingdom (南诏王) era and was officially established as Diantan Pass (滇滩关) during the Yongle period of the Ming Dynasty (明代永乐年间). By the Wanli period (万历年间) of the Ming Dynasty, it was restructured into a pass (滇滩隘), marking its significance as a border trade and military hub.

Following the full opening of the port in March 2025, Diantan Port became a secondary border port (二级口岸) between China and Myanmar, with the implementation of smart port technologies and the "pre-release, post-inspection" customs policy. Chinese citizens with a border entry-exit pass can now pass through the port.
