Politicians are facing pressure from the streets ahead of this week’s G20 summit.
The city of Nice has already been the venue of one big demonstration.
One local woman said: “We just want the poor of the planet to be taken into account, and for everything that happens on a global level to take human rights into account.”
Protest groups say they are determined to make their voices heard.
A man from Spain said: “While we’re political we are non-partisan, and we’re not anti-system, we’re anti-capitalist. We believe that there are good politicians as there are good policies, of course there are. What is happening is that the “bad” ones are the ones who have a lot of power.”
Security has been stepped up ahead of the summit, with hundreds of extra police officers on duty.
Protesters from numerous countries are descending on the French Riviera.
