Donald Trump, after calling United Nations “a club for people to have a good time” couple of days ago, has issued more statements criticizing the organization performance.

“The UN had such tremendous potential. (It is) not living up to its potential,” Trump told reporters at his Florida holiday resort, on Thursday.

“When do you see the United Nations solving problems? They don’t. They cause problems.”

The international institution, set up amid the ashes of World War II includes the World Health Organization, which helped eradicate small pox, and the Security Council, which was frozen by divisions as Syria plunged into chaos.

“If it lives up to the potential, it’s a great thing. If it doesn’t, it’s a waste of time and money,” Donald Trump said.

His comments came after the incoming UN Secretary-General Antonio Guterres said he wants to meet Trump “as soon as possible” and is “determined to establish a constructive dialogue with the new US administration.”

Trump will take the President office on January 20, 2017.
