"I strongly believe that ASEAN and the EU can play a more active and more forceful role in the world," the premier said in his keynote address at the opening ceremony of the 17th ASEAN-EU Ministerial Meeting (AEMM) at Chaktomuk Conference Hall.
"There is no room for a passive role for us, and we - ASEAN and the EU collectively - need to take on the global challenges with head on," he added.
The 17th AEMM which opened here Thursday will focus on ASEAN-EU's enhanced partnership and cooperation, as well as the world economic and financial crisis and other regional and international issues.
The meeting under the theme of "ASEAN-EU Partnership for Peace, Economic Growth and Development" is also scheduled to address issues of ASEAN integration, food and energy security, and the environment.
Hun Sen, in his speech, reviewed and spoke highly of the ASEAN-EU cooperation, saying "our close relations at present are becoming ever stronger and covering a wide range of areas."
The premier also underlined six areas for further enhancing the cooperation and partnership between the ASEAN and EU, such as continuing implementing the ASEAN-EU Action Plan, moving quickly to realize the EU/EC's accession to the TAC (the Treaty of Amity and Cooperation in Southeast Asia), supporting each other in the areas of integration and the community building process, and strengthening ASEAN-EU cooperation in the regional and international forum.
On the issue of the global economic and financial crisis, Hun Sen said "the current crisis presents both the danger and the opportunity for some countries, particularly those in the developing world."
But he warned that "the danger is that some countries may resort to protectionism." He asked to "reform the international financial institutions" to serve the interests of all.
