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. <br/><br/>Mr Videgaray said, a tax on Mexican imports to the United States is not a way to make Mexico pay for the wall, but to a way make the North American consumer pay for it through more expensive avocados, washing machines, televisions. He also stressed that paying for Mr Trump's wall is not negotiable for Mexico. <br/><br/>The Mexican President earlier cancelled a visit to the US over the row of who would pay for the barrier.<br/><br/>The planned wall was one of Mr Trump's key election campaign pledges.<br/>Earlier this week, the President signed an executive order to create a wall along the 2,000-mile (3,200km) US-Mexico border. <br/><br/>White House spokesman Sean Spicer said a 20% tax could generate approximately $10bn ('8bn) in tax revenue per year.
