The International Atomic Energy Agency welcomed the joint statement of US President Donald Trump and North Korean Leader Kim Jong Un on Tuesday and said it was prepared to undertake verification activities.

Trump and Kim pledged to work toward complete denuclearisation of the Korean peninsula and Washington committed to provide security guarantees.

"The International Atomic Energy Agency stands ready to undertake any verification activities in the DPRK (North Korea) that it may be requested to conduct by the countries concerned, subject to authorisation by the IAEA’s Board of Governors," Director General Yukiya Amano said in a statement.
