U.S. Secretary of State John Kerry arrived in South Korea on Friday for a trip likely to focus on North Korea's recent nuclear threats and provocations.
Kerry, who landed in Seoul, is about 30 miles (48 kilometers) from the demilitarized zone that separates the two countries. The Korean peninsula is rife with tensions over the belligerent threats issued by Pyongyang.
Shortly after his arrival, Kerry told reporters at a news conference with the South Korean foreign minister that the United States and South Korea agree that North Korea will not be accepted as a nuclear power.
"The rhetoric that we are hearing is simply unacceptable,” Kerry said.
Kerry also said that the United States is prepared to enter into talks with North Korea, but only if the North is serious about negotiating the denuclearization of the Korean peninsula.
