President Donald Trump is meeting on Thursday with Henry Kissinger, the 94-year-old elder statesman who served as Secretary of State and National Security Advisor under the administrations of Richard Nixon and Gerald Ford.

Trump revealed the powwow in a tweet in which he said he and Kissinger will chat about three world hotspots: North Korea, China and the Middle East.

I will be meeting with Henry Kissinger at 1:45pm. Will be discussing North Korea, China and the Middle East. — Donald J. Trump (@realDonaldTrump) February 8, 2018

Kissinger has been vocal in recent days about various world issues.

Last month, he said if North Korea is allowed to keep its nuclear weapons, other nations will seek them too as a way "for achieving international prominence and the upper hand."

He made the remarks as he appeared along with the former State Department chief in the Reagan administration, George Shultz, and President George W. Bush's former deputy secretary of state, Richard Armitage, before the Senate Arms Committee.
