The billionaire businessman sparked controversy during the long election campaign with some of his proposals which he may now enact.
Launch trade war with China by imposing hefty fees on imports
One of Trump’s first acts as President could be to launch a trade war with China, which he blames for the loss of American manufacturing jobs.
He is threatening to impose hefty fees on Chinese and Mexican imports. At present, the Americans buy more from the Chinese than they sell, and the gap is widening.
He argues that a tax of 45% on Chinese goods would raise billions of dollars and bring manufacturing jobs back to America.
However, experts have warned that these steep taxes, or tariffs, would lead to a surge in the prices of basic goods.
Some predict that China would retaliate, taxing American goods and sparking an all out trade war. A feud between the world’s two largest economies could have devastating economic consequences worldwide.
Build huge 1,900 mile wall along US-Mexican border
Trump’s headline policy is to build a wall along the 1,900 mile US-Mexican border.
The wall would be 35 to 50 feet high, and be intended to stop the flow of illegal migrants from Mexico.
Trump has said the wall’s $10 billion (£8.2 billion) construction bill would be paid for by the Mexican government.
By blocking money transfers from the US to Mexico, Trump says he will force Mexico to pay.
Mexican President Enrique Peña Nieto has been adamant that Mexico will not foot the bill, saying “Mexico will never pay for a wall.”
Former Mexican president Vicente Fox used stronger language, saying “I’m not paying for that f****** wall.”
Ban ALL Muslims from entering the United States
One of the most controversial moments of the campaign came when Trump vowed to ban all Muslims from entering the United States.
His controversial plans even drew widespread criticism from his own party.
Mike Pence , Trump’s running mate, called it “offensive and unconstitutional” and claimed that Trump no longer wanted to implement the ban.
There have been signs that Trump is rowing back on the issue. In the second presidential debate he said he was in favour of “extreme vetting” of migrants, but has not removed the statement announcing the ban from his campaign website.
Abolish Obamacare which provides millions with affordable health insurance
Trump has said that he will abolish the Affordable Care Act, known as Obamacare.
In its place, Trump wants a greater role for tax-free savings accounts to pay for health insurance.
Obamacare provided millions of Americans with affordable health insurance, but is extremely unpopular amongst conservatives, who see it as government meddling in the free market.
Critics claim that Obamacare has pushed up the cost of care, forced people to buy health insurance and led to the rationing of care.
Trump, along with the vast majority of the Republican Party, want to see a greater role for private enterprise in health care. He plans to increase competition in the industry by allowing firms to sell health insurance across state lines.
Ban the use of federal funds to pay for abortions
Trump has flip-flopped on the issue of abortion.
In 1999, he described himself as “very pro-choice”, but has since changed his stance considerably.
When asked his position on abortion in March 2016, he replied that “there has to be some sort of punishment” for women who have abortions.
Two days later, he changed his position, saying that he would not change federal law, leaving the issue up to individual states.
Trump’s running mate, Mike Pence , has since reiterated Trump’s pro-life position. Trump has said that he wants to permanently ban the use of federal funds to pay for abortions, except in cases of incest or rape, or to save the life of the mother.
Will nominate Supreme Court judges to DEFEND gun rights
Trump has voiced strong opposition to any attempts to limit the ownership of guns, and has vowed to nominate Supreme Court judges who will defend gun rights.
Many Republicans are strongly in favour of defending the Second Amendment, which guarantees the right of Americans to “keep and bear arms.”
The Republican candidate is opposed to a ban on assault weapons, and has received the endorsement of the National Rifle Association.
He has blamed mass shootings, such as the racially motivated murders in Charleston, South Carolina, on poor mental health care.
However, Trump has called for a ban on the sale of guns to people on terrorist watch-lists, a policy strongly opposed by the National Rifle Association.
Bomb the hell out of ISIS’
In the Middle East, Trump has promised to use a firm hand against Islamic State, increasing funding for the military and bombing the group’s strongholds.
The main focus of Trump’s foreign policy would be the fight against Islamic State. He’s promising to dramatically increase funding for the military, and bomb jihadist strongholds.
However, he has been criticised for saying that the US should not automatically defend NATO states, arguing that the alliance is outdated and “costing us a fortune”.
This would be a reversal of historic American policy, and could signal a dramatic scaling down of US intervention abroad.
