The 3+3 is a proposed treaty between Japan, ROK (Republic of Korea), and DPRK (Democratic People’s Republic of Korea) to create a Nuclear Weapon Free Zone (NWFZ), with Negative Security Assurances (NSAs) guaranteed by the US, China, and Russia, not to attack or threaten the area by nuclear weapons. It is based on the definition of the NWFZ set forth by the UN General Assembly in 1975.
