Only 50 days remain until the start of the high profile Nuclear Security Summit in Seoul.
This is the second of its kind with the inaugural conference held two years ago in Washington D.C. launched by US President Barack Obama.
Negotiators from the participating 50 nations have been trying to hammer out the Seoul Communique that will be adopted at the end of the two-day summit kicking off on March 26.
Sources say the document will likely contain guidelines on reducing the amount of highly enriched uranium and plutonium around the world.
Also, they will highlight strengthening safety measures at nuclear power plants in light of the multiple meltdowns in Fukushima, Japan last year.
50 Heads of State and more than 10,000 people from those countries are expected to take part, making it the largest diplomatic conference to be held in Korea.
