South Korea's deputy prime minister has called on governments to show the value of international cooperation as a Chinese-led Asian infrastructure investment bank held its first annual meeting following Britain's vote to leave the European Union.

Officials of dozens of governments including Britain attended the Asian Infrastructure Investment Bank meeting Saturday. The bank was launched this year to finance construction of roads, ports and other infrastructure in Asian countries.

Speaking at an opening ceremony, Deputy Prime Minister Yoo Il-ho of South Korea said the British vote was "a big blow to those who believe a more integrated world economy is beneficial."

Yoo said, "We should use this opportunity to show that we can cooperate to overcome challenges and achieve common prosperity."
