The US president also announced a tough crackdown on immigration at the US-Mexico border.
U.S. President Donald Trump announced Monday a tough immigration crackdown that includes sending the military to help guard the U.S.-Mexico border, ending asylum at the border and eliminating citizenship for children born to parents in the country illegally, among other promises for the next four years of his new administration.
In his first speech, Trump promised to invoke the Alien Enemies Act of 1798 to combat gangs and criminal networks.
In his inaugural address, he said he would declare a national emergency on the border with Mexico and stop the illegal entry of migrants, as part of a series of decrees.
Insists on changing the name of the Gulf of Mexico
One of the first executive orders of the new administration will be to rename the Gulf of Mexico as the Gulf of America, the president said Monday.
In addition to statements made during his inauguration, at a press conference at Mar-a-Lago in January, Trump declared the name change to be "appropriate." "We're going to change it, because we do most of the work there, and it's ours," he said.
Mexican President Claudia Sheinbaum has stated in her morning press conferences that the name of the Gulf of Mexico is recognized by the United Nations (UN). This was in response to Trump's idea of changing it to the "Gulf of America."
Tariffs: Should they be allowed or not?
The new US president said that "instead of taxing our citizens to make other countries rich, we will impose tariffs on other countries to make our citizens richer."
Trump did not provide further details on Monday about what the new tariffs would be, but he did announce the creation of the External Revenue Service to collect the tariffs.
Recovery of the Panama Canal
"We gave the Canal to Panama and we are going to get it back," Donald Trump promised in his inaugural address.
"China is operating the Panama Canal and we did not give it to China," insisted the Republican, who in recent weeks has not ruled out the use of military force to take control of the interoceanic waterway.
Shortly before taking office, Trump had repeatedly said he wanted to seize control of the Panama Canal, which was built by the United States and opened in 1914, then transferred to the Central American country in 1999.
"We have been badly treated with this foolish gift that should never have been given. The promise that Panama made to us has not been kept," Trump said in his inaugural address shortly after his swearing-in.
Trump has criticized then-President Jimmy Carter's 1977 agreement that resulted in the transfer of control of the canal to Panama in 1999.
"We're going to get it back," he promised amid applause.
"The purpose of our agreement and the spirit of our treaty have been completely violated. American ships are being severely overtariffed and are not being treated fairly in any way, including the U.S. Navy," he said.
The Republican became the 47th president in the history of the United States after being sworn into office in a symbolic ceremony that allows him to return to the White House four years later and which de facto means the end of Democrat Joe Biden's term.
Trump, 78, took the oath on a family Bible, before which he recited the constitutional formula in the presence of Supreme Court Chief Justice John Roberts: "I do solemnly swear that I will faithfully execute the office of President of the United States, and will use my best efforts to preserve, protect and defend the Constitution of the United States."
