FRANKFURT--German retailer Metro AG (MEO.XE) said Thursday it has agreed to enter an international purchasing partnership with Groupe Auchan to combine the strengths of the French retailer and Metro's wholesale and food-retail divisions.

According to the agreement, the companies will jointly negotiate on specific international services and conditions for suppliers of branded consumer products globally. They will also jointly purchase non-food products that each company will resell individually under its own brand labels or as no-name labels.

Electronic consumer products are excluded from these two agreements, Metro said.

"This strategic buying partnership allows us to face the challenges of trade globalisation and the changing procurement markets," Auchan Chairman Vianney Mulliez said in a statement.

The cooperation agreement will be effective from November 2014 for negotiations related to 2015. Financial details weren't disclosed.
