Former U.S. Secretary of State Henry Kissinger was released from a hospital in the South Korean capital Sunday after recovering from stomach pains, a hospital spokesman said.
Kissinger's condition was "not serious" while he was being treated at Seoul's Severance Hospital and he had recovered after a day of medical treatment, spokesman Han Jin-ho said.
Han said Kissinger didn't receive any major treatment like surgery, but didn't elaborate.
A healthy-looking Kissinger thanked nurses and shook hands with them before leaving the hospital. He didn't speak to journalists waiting for him.
The 86-year-old Nobel Peace Prize laureate arrived in Seoul earlier in the week to attend a security forum. He also met with South Korea's President Lee Myung-bak.
As secretary of state, he helped open formal relations between China and the U.S. and arms-control agreements with the Soviet Union under Presidents Richard Nixon and Gerald Ford.
He shared the Nobel Peace Prize with Le Duc Tho for the 1973 cease-fire that led to the withdrawal of U.S. troops from Vietnam.
