Sinuiju in the context of "McCune–Reischauer"

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.

Dandong is a coastal prefecture-level city in southeastern Liaoning, in the northeastern region of China.

It is the largest Chinese border city, facing Sinuiju, North Korea, across the Yalu River, which demarcates the Sino-North Korean border. To the southwest of the city, the river flows into Korea Bay. Dandong has therefore had a dynamic history because of its strategic location for the northeast's rich natural resources and because of its convenient access to the ocean. It is designated as a major export production centre for the province, and is a port city connected by rail with Shenyang and Sinuiju. A significant amount of trade with North Korea flows through the city.

The Sino-Korean Friendship Bridge, or China–North Korea Friendship Bridge, is a bridge across the Yalu or Amnok River on the China–North Korea border. It connects the cities of Dandong in China and Sinuiju of North Korea, by railway and roadway but pedestrians are not allowed to cross between either side. The bridge serves as one of the few ways to enter or leave North Korea.

It was renamed to its current name from the Yalu (Amnok) River Bridge in 1990. The bridge was constructed by the Imperial Japanese Army (IJA) between April 1937 and May 1943 during its occupation of Korea and its puppet state of Manchukuo (now northeast China). Further downstream, construction work on the New Yalu River Bridge began in October 2010.

North Pyongan Province (also spelled North P'yŏngan; Korean: 평안북도; MR: Phyŏnganbukto; IPA: [pʰjʌŋanbuk̚t͈o]) is a western province of North Korea. The province was formed in 1896 from the northern half of the former P'yŏng'an Province, remained a province of Korea until 1945, then became a province of North Korea. Its capital is Sinŭiju. In 2002, Sinŭiju Special Administrative Region—near the city of Sinuiju—was established as a separately governed Special Administrative Region.

Sinuiju Special Administrative Region (Korean: 신의주특별행정구) was a planned special administrative region (SAR) of North Korea based in the city of Sinuiju. Proclaimed in 2002, the SAR was envisioned to be directly governed, having been split off from North Pyongan Province, as is the case for "Directly Governed Cities" but has yet to be put into de facto operation.

Proposals for a special economic zone in Sinuiju to introduce market economics were first proposed to Chinese-Dutch businessman Yang Bin in 2001, who was proposed to be the zone's director. Yang later accepted the proposal on several conditions; most importantly, rather than a SEZ, the proposed area would become a special administrative region, emulating China's special administrative regions (SARs) of Hong Kong and Macau. Under this proposal, the Sinuiju SAR would have its own "Basic Law" (기본법; Kibonpŏp), passport, flag and seal, and have large autonomy in all areas except foreign policy and defense. Though reluctant, North Korean officials eventually acceded to Yang's proposals.

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.
