During Prime Minister Pham Minh Chinh's visit to China in 2023, a Framework Agreement was signed by leaders of Lang Son province (Vietnam) and the government of the Guangxi Zhuang Autonomous Region (China) to establish smart border gates at the Huu Nghi International Border Gate. The goal of the smart border gate is to increase the capacity and efficiency of customs clearance at the border gate between Vietnam and China, ultimately contributing to the socio-economic development of the region and country. Lang Son province is a key transshipment area for Vietnam-China import and export goods, playing an important role in promoting economic and trade exchanges between the two countries and ASEAN.
