Obama thanks the world for nuclear security cooperation

The nuclear security summit was initiated by President Obama in 2010 and began after his speech in Prague (2009) where he had shared his vision of a nuclear weapons-free world.

The 2016 summit is his 4th and final nuclear summit.

52 countries including four international organisations- UN, International Criminal Police Organisation (Interpol), International Atomic Energy Agency and the European Union participated in the event.

In spite of all the progress made, US President said that further negotiations needed to be made with Russia for nuclear reductions.

Russia- one of the world's biggest nuclear power boycotted the summit.

Further, Obama said that dealing with North Korea's nuclear ambitions was another need of the hour.

Obama agreed that complete nuclear disarmament "perhaps will not happen in my lifetime."

Canadian PM Trudeau made a $42 million pledge towards nuclear security.

$26.5 million was sanctioned for sustaining global efforts for the interception of illegal nuclear trafficking.

$6.6 million was allocated to support the International Atomic Energy Agency's security fund dealing with cyber-security at nuclear facilities.

$5.7 million for enhancement of physical security of nuclear facilities and $2.3 million to increase security of radioactive sources.

Speaking on the 2nd day of the Nuclear Security Summit, Modi announced initiatives being taken by Indian government for nuclear security and non-proliferation.

PM Modi said India had deployed technology to deter nuclear terrorism and nuclear smuggling.

These include "physical and cyber barriers, technological approaches, setting up a facility for medical grade 'Moly-99' using low enriched Uranium and using vitrified forms of vulnerable radioisotopes".

Speaking at the nuclear summit, President Obama congratulated all 50 countries for their participation.

He hailed the fortifying treaties and international partnerships towards nuclear security.

Obama said that the support and an "all-out elimination of plutonium and highly enriched uranium from 14 nations and Taiwan" since the first Nuclear Security Summit six years ago was their greatest achievement.
