The city of Paris has criticised LafargeHolcim for its willingness to supply material for the wall that US President Donald Trump plans to build along the Mexican border.

The French capital’s governing council voted on Tuesday to stop working with the world’s biggest cement maker for as long as the company won’t respect the city’s ethical standards, a spokeswoman said by phone on Wednesday. It will start by ending a longstanding arrangement to take sand from LafargeHolcim for artificial beaches along the river Seine.

The city had already decided it would replace sand with grass and plants this year, yet agreed to shun the cement maker anyway.
