Sinŭiju, is a city in North Korea which faces Dandong, Liaoning, China, across the international border of the Yalu River. It is the capital of North P'yŏngan province. Part of the city is included in the Sinŭiju Special Administrative Region, which was established in 2002 to experiment with introducing a market economy. In recent years, the city, despite lagging behind the development in the capital Pyongyang, has seen a small construction boom and increasing tourism from China.
