Mexican President Enrique Pena Nieto has compared the rhetoric of US Republican presidential candidate Donald Trump to that of German Nazi leader Adolf Hitler.
In an interview with Mexican daily Excelsior, he called Mr Trump's rhetoric "strident".
He added that "that's how [Italian fascist leader] Mussolini got in, that's how Hitler got in".
The Mexican leader also said that Mr Trump had hurt US-Mexico relations.
Donald Trump has said that if he is elected he will build a wall along the US-Mexico border to keep migrants from crossing into the US illegally.
The Republican candidate has also insisted that Mexico would pay for the border wall, which President Pena Nieto dismissed out of hand.
He said there was "no scenario" under which Mexico would ever pay for such a wall.
Mr Trump, who has made the fight against illegal immigration the main plank of his campaign, outraged Mexicans last June when he called undocumented Mexican migrants "criminals" and "rapists".
Ominous situations'
President Pena Nieto said Mr Trump offered "very easy, simple solutions to problems that are obviously not that easy to solve"
"And there have been episodes in human history, unfortunately, where these expressions of this strident rhetoric have only led to very ominous situations in the history of humanity," he said.
"That's how Mussolini got in, that's how Hitler got in, they took advantage of a situation, a problem perhaps, which humanity was going through at the time, after an economic crisis," he added.
President Pena Nieto, who had up until now avoided commenting on Mr Trump's candidacy, insisted he would be "absolutely respectful" of the US political process.
His predecessors in office, however, have been more outspoken.
Former President Vicente Fox used an expletive on live television when he said Mexico would not pay for the border wall proposed by Mr Trump.
Felipe Calderon, who governed from 2006 to 2012, also dismissed the idea saying: "Mexican people, we are not going to pay any single cent for such a stupid wall!"

The funeral has taken place of the murdered Honduran indigenous activist, Berta Caceres.
An award-winning environmentalist, she was killed on Thursday by gunmen who broke into her house.
Her killing was internationally condemned, with Oscar-winner Leonardo de Caprio tweeting that Ms Caceres' work should be honoured.
She had led protests against a hydro-dam project and her son said she was killed for economic reasons.
Her family say she had been living with constant and serious threats for months from police, politicians and construction companies.
Thousands of people carried her coffin through her home town of La Esperanza, about 200km (124 miles) from the capital, Tegucigalpa.
A mother of four who would have been 45 on Friday, Ms Caceres rose to prominence when she led the fight of the Lenca indigenous people against a hydroelectric dam project that could flood large area of native lands and cut off water supplies to hundreds.
Despite living with constant threats she won the 2015 Goldman Environmental Prize, considered the world's top award for grassroots environmental activism.
Berta Caceres' family has accused the authorities of trying to portray her death as a random murder instead of an assassination because of her activism against large mining and environmental companies.
The week before her murder she had denounced the murder of four indigenous leaders in the Lenca community.
"This is a political crime," said Berta's daughter, Olivia Zuniga Caceres. "We totally deny that this was a crime of passion."
Police say they have arrested a man and minor who they say belonged to an organisation founded by Ms Caceres and allege they are responsible for the murder.
Olivia Zuniga says the family have contacted international investigators to look into her mother's death.
"This will ensure that there is no more corruption, no more bribery, and will give us confidence."
She said the funeral was a celebration of Berta Caceres's life. "She lived and died fighting. We don't feel sad, we don't feel fear, we are going to demand justice until the end." she said.
