A protester shields himself from the water canon with an umbrella during a protest in Seoul, S. Korea on June 25, 2008. South Korea lifted its ban on imports of U.S. beef Thursday, and President Lee Myung-bak called on the country to move past the dispute, which has paralyzed his government with weeks of tumultuous protests. Critics were outraged against Lee, saying he made too many concessions to Washington and ignored public concerns about mad cow disease.
