Sino-Korean Friendship Bridge in the context of "China–North Korea border"

The People's Republic of China (PRC) shares land borders with 14 countries (tied with Russia for the most in the world): North Korea, Russia, Mongolia, Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan, Pakistan, India, Nepal, Bhutan, Myanmar, Laos, and Vietnam, and with two Special administrative regions of China, Hong Kong and Macao. The land borders, counterclockwise from northeast to southwest, are the China–North Korea border, the eastern segment of the China–Russia border, the China–Mongolia border, the western segment of the China–Russia border, the China–Kazakhstan border, the China–Kyrgyzstan border, the China–Tajikistan border, the China–Afghanistan border, the China–Pakistan border, the western segment of the China–India border (the most contested of the Sino-Indian border dispute), the China–Nepal border, the central segment of the China–India border (Sikkim), the China–Bhutan border, the eastern segment of the China–India border, the China–Myanmar border, the China–Laos border, the China–Vietnam border, a 3-kilometre (1.9 mi) internal border with Macau, a Portuguese territory until 1999, and a 30-kilometre (19 mi) internal border with the special administrative region of Hong Kong, which was a British dependency before 1997.

To the west, China has maritime borders with North Korea, Japan and contested limits with Taiwan and other countries in the South China Sea, among other territorial disputes.

The New Yalu River Bridge (Chinese: 新鸭绿江大桥; Korean: 신압록강다리), or Korea-China Amnok River Bridge (Korean: 조중압록강다리), is a road bridge across the Yalu River between Dandong, Liaoning Province, China, and Sinuiju, North Korea. The cable-stayed bridge, which is 3 kilometers (1.9 mi) long including the supporting roads, is intended as a replacement for the Sino-Korean Friendship Bridge. Construction began in October 2011 and is mostly complete and connected with Xingdan Road, but the project stalled between 2014 and 2019, with work unfinished on the North Korean side. By 2021, construction on the North Korean side has been mostly completed, with the bridge being expected to open soon.
