Mexico has condemned a US suggestion that it may impose a 20% tax on Mexican imports to pay for President Donald Trump’s planned border wall.
Foreign Minister Luis Videgaray said such a tax would make Mexican imports more expensive for US consumers and they would end up paying for the wall.
The Mexican president earlier cancelled a visit to the US over the row of who would pay for the barrier.
The planned wall was one of Mr Trump’s key election campaign pledges.
Earlier this week, the president signed an executive order to create a wall along the 2,000-mile (3,200km) US-Mexico border.
