The General Meeting of Members of the Boao Forum for Asia elected the new board of directors in the morning, and Ban replaced Yasuo Fukuda, former Japanese prime minister, to become the new chairman of the 19-member Board of Directors.

According to a resolution of the new board, Fukuda, along with other 10 outgoing members of the previous board, are invited to the Council of Advisers.

Ban said while addressing a meeting on Monday that joint efforts are needed to achieve the goal of sustainable development and deal with climate change.

He warned that if the countries failed to make joint efforts to cope with common threats, the whole world will sink.

He called for new type of multilateral cooperation to share development opportunities, achieve common prosperity, and boost interconnectivity of infrastructure.
