In late 2009, Sarkozy appointed Lang his special envoy to North Korea, following a similar assignment earlier in the year to Cuba. Lang travelled to Pyongyang on 9 November 2009 for a self-described "listening mission" aimed at exploring bilateral ties and discussing the North Korean nuclear program, among other things. Lang briefed American officials including Deputy Secretary of State James Steinberg and special envoy Sung Kim, as well as ambassadors of countries involved such as Russia, before the assignment was publicly announced. Some critics questioned Lang's qualifications, but Lang said he would be driven by his "intuition" that change was afoot in North Korea.
