BMW sees no reason to change its plans for Mexico in the wake of US threats to slap duties on Mexican imports, a board member of the German carmaker has said.

Oliver Zipse also said that the company sells cars globally despite tariffs placed by most countries on imported vehicles. 

The car maker also foresees no immediate change to its investment plans for North America, said Mr Zipse, BMW board member in charge of production. 

He was in the central Mexican city of San Luis Potosi for the inauguration of a $1 billion BMW plant. 

But other car makers have warned that the imposition of punitive duties on Mexican imports could be damaging to the industry, with Toyota saying earlier this week that the proposal could cost its major suppliers $1 billion. 

Last week, Trump said Mexico must take a harder line on stopping the flow of migrants across the US-Mexico border or face 5% tariffs on all its exports to the US from June 10, rising to as much as 25% later this year. 

BMW is producing its 3 series at the San Luis plant, which started up in April and has a capacity of up to 175,000 vehicles per year. 

The company plans to ship 2,000 vehicles to the US from the new Mexican plant in April to July. 

"It will increase our already strong footprint in North America and provide us with further model variety in addition to our big SAV (sports activity vehicle) production plant in Spartanburg," Zipse said. 

BMW's SAV is a form of sport utility vehicle (SUV). 

Asked if BMW will try to lobby US officials to drop the tariffs, Zipse suggested that the company will let its robust presence in the US do the talking. 

He noted that BMW's plant in Spartanburg, South Carolina, is its largest in the world, with 14,000 direct employees.
