May 9 (UPI) -- South Korea's Trade, Industry and Energy Minister Ahn Duk-geun flew to the Czech Republic Tuesday to attend a contract signing ceremony for a new nuclear power plant. Czech utility firm CEZ was slated to ink the deal, worth at least $18 billion, on Wednesday under which South Korea's state-run KHNP would build two nuclear reactors in the East European country. However, the event was abruptly canceled after a Czech court issued an injunction, blocking CEZ from closing the deal
