Chung Dong-young (Korean: 정동영; born 27 July 1953) is a politician and was the United New Democratic Party nominee for President of South Korea in 2007.

Some people criticize that he has not taken a tougher stance on North Korea, and that he had rhetorical clashes with the United States that helped weaken relations between the two countries.

The contention that he had impeded on the relationship between South Korea and the United States can be counter proven by the process he had made the Keasong Complex realized.

The Keasong Complex could not have made possible unless the then Bush administer had authorized the approve of foreign materials flowing into North Korea.

The realization of the complex in the middle of hawk driven period of "axis of evil" can only be correctly explained by the quick and wide approach by the then Unification Ministry and the minister Chung to convince the US government and the Korean counterpart.

The loss was attributed primarily to the people's disappointment of the economic situation and its dealings and continuous political strife under the Roh Mu-hyun government as well as the unsuccessful campaign strategies that overly relied on criticizing the other candidate, Lee Myung-bak.
