Donald Trump has been vocal and adamant on his stand on certain issues like foreign policy and national security. For his supporters, the man is a patriot who has an utmost devotion to the interest of the United States. On the other side of the spectrum, people portray him as some jingoistic xenophobe.

The Republican candidate drew the ire of a lot of people when he called for a "total and complete shutdown of Muslims" entering the U.S., and the building of a wall along the southern border of the country to shut out illegal immigrants and drugs.

Another report also surfaced that some of the foreign diplomats around the world have expressed their concern over some of the statements made by the outspoken GOP frontrunner. Here are some of the world leaders who have showed their disapproval of Trump.

UK Prime Minister David Cameron

"I think his remarks are divisive, stupid and wrong," Cameron said back in 2015. "I think if he came to visit our country, he'd unite us all against him."

However, if a petition calling for Trump to be declared persona non grata in the country materialized, then there won't be any need for unity against the billionaire from New York.

Mexican President Enrique Peña Nieto

President Nieto joined his predecessors in criticizing Trump regarding the wall and saying that Mexicans won't pay for it. He even made a comparison of Trump to dictators Benito Mussolini and Adolf Hitler.

"There have been episodes in the history of humanity, unfortunately, where these expressions, this strident rhetoric has only really been [a] very fateful stage in the history of mankind," he said.

Pope Francis

Even the Vatican leader had something to say on Trump's plan of deporting more immigrants and building a wall.

"A person who thinks only about building walls, wherever they may be, and not building bridges, is not Christian," the Roman catholic church leader said.

Turkey's President Recep Tayyip Erdogan

On the call for Muslims to be barred from entering the United States, President Erdogan said, "A successful politician would not make such statement, as there are millions of Muslims living in the U.S. I don't know whether or not he'll win, but let's suppose he won. What will happen? Will he set aside all relationships with Muslim countries? A politician shouldn't talk like this."

France's Prime Minister Manuel Valls

The French leader took to Twitter his expression of objection for Trump on his Muslim ban statements last December 2015. According to him, Trump is causing the spread of hatred among people when the true enemy should be radical Islamism.

Meanwhile, not everyone from outside of the United States is not so fond of the GOP frontrunner. As it turned out, there is no cold war between Trump and Russia's President Vladimir Putin, but a mutual admiration for one another.

For his part, the Russian leader referred to Trump as "really brilliant and talented" and "the absolute leader in the presidential race." Trump, on the other hand said, "I think that I would probably get along with [Putin] very well."
