Youyiguan, located in the southwest of Chongzuo city in Guangxi Zhuang autonomous region along the China-Vietnam border, is known as the "southern gateway of China." Since ancient times, it has been an important land route to Vietnam. At present, China's imports and exports with ASEAN have grown for nine consecutive years, and the two sides have remained each other's largest trading partners for five consecutive years. Youyiguan is one of the most convenient land routes to ASEAN.

　　Across Guangxi, many ports have achieved fast customs clearance: in Pingxiang, local specialties from Guangxi are transported on the China-Vietnam cross-border express freight train, reaching Hanoi in just 14 hours; in Nanning, cross-border e-commerce goods clear customs in only one hour; at Qinzhou Port, freight transported by rail and sea reaches Haiphong Port in Vietnam in just eight hours via the "cross-border direct shipping service."
