WASHINGTON (AP) -- The United States and South Korea said Monday that high-level talks meant to resolve a crisis in Seoul over renewing imports of American beef would continue.
The announcement of more discussions came hours after the U.S. Trade Representative's office said that weekend talks in Washington had ended without a resolution and that South Korean Trade Minister Kim Jong-hoon would return home.
The talks, which focused on the importation of U.S. beef from cattle younger than 30 months of age, came as thousands of people protested in Seoul, demanding that a beef import deal settled in April be renegotiated and urging South Korean President Lee Myung-bak to resign.
Kim headed to New York late on Sunday, where he was to fly back to Seoul, but the U.S. proposed that the two sides hold more consultations, South Korea said. The U.S. also later conveyed a similar message to South Korea through its embassy in Seoul.
U.S. Trade Representative spokeswoman Gretchen Hamel said Monday that Kim would have more talks with U.S. officials, but she had no other immediate details on the last-minute change in schedule.
Before Kim's decision to return to Washington, Hamel said Sunday that the trade envoys had held ''frank and candid discussions'' Friday and Saturday, but, ''in order to find a mutually acceptable solution, both sides need more time to look into technical issues.''
Lee has vowed not to allow the import of beef from cattle older than 30 months. Scientists think infection levels of mad cow disease increase with age.
The Bush administration has said that it will not renegotiate an accord that was supposed to have settled a major irritant in ties between the allies. But Washington has said it supports beef packaging labels that would show the ages of slaughtered cows.
Lee said he has received a positive reply from the U.S. on measures under which the American beef industry would voluntarily not ship meat from cattle older than 30 months. Lee called the voluntary restraint the most rational measure to resolve the beef dispute.
American beef processors have said they are willing to label beef shipments bound for South Korea.
South Korea was the third-largest overseas market for U.S. beef until it banned imports after a case of mad cow disease was detected in 2003, the first of three confirmed cases in the United States.
Seoul's agreement to reopen its market for U.S. beef, which came just hours before Lee held his first summit with President Bush, was widely seen as a concession aimed at getting the United States to approve a broader free trade deal.
Both Seoul and Washington have repeatedly insisted that U.S. beef is safe, citing the Paris-based World Organization for Animal Health. But Lee has come under intense public fire for allegedly ignoring concerns over the safety of U.S. beef.
The entire South Korean Cabinet offered to resign last week in an apparent attempt to dampen public anger, but late-night vigils and street rallies have continued.
A crowd estimated by police at about 2,000 rallied Sunday night near the city hall and marched through Seoul.
Mad cow disease is the common term for a brain-wasting disease in cattle called bovine spongiform encephalopathy, or BSE. In people, eating meat contaminated with BSE is linked to variant Creutzfeldt-Jakob Disease, a rare and deadly nerve disease.
