Close to a decade after it opened, the inter-Korean customs office near the Gyeongui rail line north of Seoul processed the millionth South Korean this week.

A small ceremony held Wednesday marked the millionth visitor to North Korea, who works for one of the businesses operating in the inter-Korean Kaesong Industrial Complex.

The land border in Gyeonggi Province, which opened in March 2003, has mostly been used by government officials and business representatives. Despite strained inter-Korean relations, business continues at Kaesong, with some 400 daily visitors from the South Korean side.
