Nanning–Kunming high-speed railway (formerly known as the Yunnan–Guangxi high-speed railway[1]) is a high-speed railway connecting Nanning and Kunming, respectively the capitals of the Guangxi Zhuang Autonomous Region and Yunnan Province. It will have a total length of {{convert|715.8|km|abbr=on}} of electrified double-track railways, built to the Grade 1 standard. Positioned as part of China's "long-term railway network plan", to improve the layout and the development of South-Western China with critical infrastructure, it will be Yunnan Province's first high-speed transport corridor to the sea. With future Pan-Asian railways to Laos, Thailand and Vietnam planned or under construction, this railway will be seen as a crucial link between the economic powerhouse of the Pearl River Delta Economic Zone and Indochina under the One Belt-One Road initiative.
