In 2005, during investigations into the U.N.'s Oil-for-Food Programme, evidence procured by federal investigators and the U.N.-authorized inquiry of Paul Volcker showed that in 1997, while working for Annan, Strong had endorsed a check for $988,885, made out to "Mr. M. Strong," issued by a Jordanian bank. It was reported that the check was hand-delivered to Mr. Strong by a South Korean businessman, Tongsun Park, who in 2006 was convicted in New York federal court of conspiring to bribe U.N. officials to rig Oil-for-Food in favor of Saddam Hussein. Mr. Strong was never accused of any wrongdoing. During the inquiry, Strong stepped down from his U.N. post, stating that he would "sideline himself until the cloud was removed". Strong now lives in Beijing.
