50,000 protesters are expected in Geneva on Sunday, prompting authorities to tighten security ahead of the G7 summit across the border in Evian-les-Bains.
27 France-Switzerland border crossings will be closed or controlled from Friday evening, while Switzerland is mobilizing 4,000 soldiers; France is deploying 8,000 police for the summit starting Monday.
2,000 square metres of wooden panels have already been installed on Geneva shopfronts, with residents and businesses citing memories of damage during clashes around the 2013 Evian G8 summit.
20 million Swiss francs is the likely security bill for Geneva's canton, as local businesses say the protest preparations are already cutting trade and work for several days.
