“Well, we’re watching those votes,” he added. “Let them vote against us; we’ll save a lot. We don’t care," Trump told the reporters at the White House, according to Reuters.

Trump has threatened to cut U.S. aid to countries defying the recent U.S. decision of declaring Jerusalem as Israel's capital.

“All of these nations that take our money and then they vote against us at the Security Council or they vote against us, potentially, at the Assembly, they take hundreds of millions of dollars and even billions of dollars and then they vote against us," Trump told the reporters at the White House, according to Reuters.

“Well, we’re watching those votes,” he added. “Let them vote against us; we’ll save a lot. We don’t care."

The decision might impact some key U.S. allies in the Middle East.

In a rare move, following the request of Arab and Muslim countries, the 193-member U.N. General Assembly has decided to hold an emergency special session on Thursday to vote on a draft resolution, which the United States vetoed on Monday in the 15-member U.N. Security Council.

Under a 1950 resolution, an emergency special session can be called to consider a matter “with a view to making appropriate recommendations to members for collective measures” if the Security Council fails to act. Only 10 such sessions have been convened thus far.

During Monday's U.N. Security Council meeting, 14 members voted in favor of the Egyptian-drafted resolution, which did not explicitly criticize the United States or Trump but expressed “deep regret at recent decisions concerning the status of Jerusalem.”

Trump's statement followed the UN Envoy Nikki Haley's statement earlier in which she issued a thinly veiled warning to the UN General Assembly members regarding a forthcoming vote on U.S. President Donald Trump's declaration of Jerusalem as the 'capital' of Israel. 

According to Reuters, U.S. Ambassador Nikki Haley sent a letter to dozens of UN states on Tuesday, issuing a warning that the United States would remember those who voted for the resolution criticizing the United States' decision on the hotly contested holy site.

“The president will be watching this vote carefully and has requested I report back on those countries who voted against us. We will take note of each and every vote on this issue,” Haley said, AFP reported.

She echoed that call in a Twitter post: The U.S. will be taking names.”

Haley issued a notice to the countries that she will report back to U.S. President Donald Trump with the names of those who support a draft resolution to reject the United States vetoing its decision to recognize Jerusalem as Israel's capital.

Palestinian UN envoy Riyad Mansour said the General Assembly would vote on a draft resolution calling for Trump’s declaration to be withdrawn.

On Monday, the United States was the only country in the 15-member U.N. Security Council to vote in favor of its stance on Jerusalem. The remaining 14 Security Council members voted in favor of an Egyptian-drafted resolution.

The latter draft expressed “deep regret at recent decisions concerning the status of Jerusalem.”

Mansour said he hoped there would be “overwhelming support” for the resolution.

"The General Assembly will say, without the fear of the veto, that the international community is refusing to accept the unilateral position of the United States," Mansour told stated.

No country has veto powers in the General Assembly. But, the United States, Britain, China, France and Russia can block any resolution.

On Dec. 6, Trump announced the United States' decision to recognize Jerusalem as Israel's capital.

The moved drew strong criticism and caused protests across the Muslim world.

Britain, France, Italy, Japan and Ukraine were among the 14 countries in the 15-member council that voted in favor of the measure.

Haley described the 14-1 vote "an insult" and warned, "it won't be forgotten."
