Prime Minister Hun Sen will attend the 32nd Asean Summit in Singapore beginning on Friday.
The premier will lead a high-level delegation, including ministers from the Foreign Affairs, Commerce and Education ministries, to the summit.
On the sidelines of the summit, the Prime Minister will hold bilateral talks with heads of delegations from other countries, the Foreign Affairs Ministry said in a statement.
Mr Hun Sen will leave the country on Friday morning and return on Saturday afternoon.
The ministry said the summit will reflect the core approaches of Asean in order to remain relevant as the regional body for the maintenance and promotion of peace, stability and prosperity.
The ministry added that the leaders of Asean member states will discuss and exchange views on building a Resilient and Innovative Asean, establishment of an Asean Smart Cities Network, Cyber Security Cooperation, Asean’s external relations, and its future directions as well as regional and international issues of common interest.
At the conclusion of the summit, a number of important documents will be presented and adopted, the ministry added.
Mr Hun Sen recently hinted that the summit may include talks over North Korean-US relations.
“It’s not just a matter concerning the two Koreas, but it’s a regional and international issue,” Mr Hun Sen said.
