South Korean President Lee Myung-bak said on Wednesday the upcoming conference on global nuclear security will help build security in Northeast Asia. "The Seoul Nuclear Security Summit will do a great deal of good in terms of security not only in South Korea but also in Northeast Asia,"Lee told reporters in a press conference marking the fourth anniversary of his inauguration. "It is of great importance that heads of some 50 countries and representatives of international organizations come together to discuss security issues in South Korea, a country under the threat of (use of) nuclear weapons," the president said, referring to the Nuclear Security Summit scheduled for March 26-27 in Seoul.

Participants of the conference will seek to formulate international norms on preventing terrorists from acquiring nuclear weapons, Lee said.

The two-day summit, which will bring together 58 heads of state and international organizations, is aimed at reducing and protecting radioactive materials and keeping terrorists at bay from nuclear materials and facilities.

Lee has extended an invitation to the Democratic People's Republic of Korea (DPRK) to attend the global forum on the condition that the country demonstrates its commitment to denuclearization.

The first nuclear security summit was held in Washington in 2010.
