Last weekend's unrest saw about 3,000 stores looted and 2,700 arrests.
France is deploying soldiers to guard sensitive buildings and support police ahead of Saturday's protests, after last weekend's cost-of-living demonstrations turned violent.
About 3,000 stores were looted and 2,700 people arrested last weekend. Police presence will be 20 per cent higher this Saturday, with helicopters, water cannons and armoured vehicles on standby.
President Emmanuel Macron has said only union-organised marches will be approved this weekend. Marseille and Lyon have banned protests and extended curfews, and three major Paris museums will close on Saturday.
The unrest has rattled markets, with the gap between French and German 10-year bond yields widening to its highest since 2011.
