South Korea and the Czech Republic agreed to cooperate on the European Union's adoption of additional sanctions against North Korea, the foreign ministry here said Wednesday.

"Czech Foreign Minister Lubomir Zaoralek shared the understanding that North Korea's nuclear test is an unpardonable, serious provocation and pledged to do all that is necessary to bring about strong sanctions and pressure from the EU in close collaboration with our (South Korean) side," the Ministry of Foreign Affairs said after Zaoralek held talks with Foreign Minister Yun Byung-se earlier in the day.

Zaoralek is visiting South Korea for a three-day trip that began Tuesday, along with a delegation of 50 businessmen and academics.

During the talks, the two foreign ministers also reaffirmed a bilateral strategic partnership, vowing closer cooperation in the fields of nuclear reactors, defense manufacturing and science technology as well as personnel exchanges between the countries, according to the ministry.

"The latest meeting, the third between Yun and Zaoralek, helped intensify cooperation with our strategic partner Czech on bilateral and regional issues," the ministry said. (Yonhap)
