Washington, Oct 23 (IANS): US Republican presidential candidate Donald Trump in Pennsylvania reiterated that he will build a wall on the Mexican border which would be financed by the US and "reimbursed" by Mexico.

The New York billionaire also emphasised that he will suspend immigration from regions known for terrorism, Efe news reported.

As the business magnate had put forward his plans for the first 100 days of his presidency during a speech at Gettysburg town on Saturday, he confirmed that his law to put an end to illegal immigration would include financing for the wall, with the complete understanding that Mexico would "reimburse" the US.

Trump also referred to his controversial idea of banning immigration from regions known for terrorism, but he gave no details about how this ruling would be applied.

Gettysburg is a place in American history where Abraham Lincoln in 1863 gave one of his most famous speeches during the Civil War. 

Trump noted that he will cancel the "billions" of dollars being paid to the UN for climate-change programmes.

Most of his proposals echoed previous announcements, such as his intention to withdraw the US from the Trans-Pacific Partnership (TPP) and renegotiate the North American Free Trade Agreement (NAFTA).

He also criticised the excessive number of regulations, particularly in matters of climate change, imposed by the Obama government.

He attacked his Democratic rival Hillary Clinton by charging her with defending the same old Washington policies.

"Clinton is not running against me," Trump said. "She's running against change and she's running against all of the American people and all of the voters."

As the US electoral campaign enters its final stage before the November 8 election, Trump seeks to gain back some of the ground he has lost in the polls following the scandals dogging him in recent weeks.
