The US and Mexico have reached an agreement to build a wall along the border to protect the border from illegal immigrants.
The pact was announced on Friday by US President Donald Trump and Mexican President Enrique Pena Nieto, as the two countries were meeting in Washington.
Trump said the wall would cost the US $12.6 billion and Mexico $2.2 billion, but Mexico’s government says it is far less expensive.
It will also include an upgrade of existing border fencing, with a barrier at the southern end of the 2,200-mile border and another at the northern end.
Pena Nieto said he would ask Congress to approve the plan, which was approved in Congress last year.
The deal is likely to boost both countries’ bilateral trade and investment, although there is still no estimate on how much money it will generate.
The agreement follows a series of high-profile incidents involving illegal immigrants in the United States, including the death of a 14-year-old boy who was caught trying to enter the country.
Mexican officials say they are investigating the death and have asked for more help from the US to find out more.
Trump and Pena Mayors meet for talks in the Oval Office on Friday.
