The Markets of Barcelona offer several international initiatives, participate in them and project their model of markets beyond our borders. They collaborate with markets on other continents to explain the management model to them, participate in projects to boost markets as a stimulus for urban development and present international conferences on various topics, among others.

During 2021, the Municipal Institute of Markets of Barcelona provided advice on the commercial viability of the Prat de Llobregat, Lloret de Mar and Vila-seca municipal markets.

In October 2021, the 7th Global Forum of the Milan Urban Food Policy Pact was also inaugurated in Barcelona, which had as its central theme the link between food and the climate emergency. More than five hundred technicians and political leaders from over two hundred cities around the world participated. On the occasion of the visit, several working meetings were held with two councillors from the City Council of the African city of Maputo, capital of Mozambique, continuing the collaboration agreements initiated in 2013 with Barcelona on the management and the modernisation of its public markets.

A month later, the Mayor of Barcelona, Ada Colau, met with the Mayor of Tunis, Souad Ben Abderrahim, to strengthen cooperation between Barcelona and Tunis and ratify the common interest to maintain cooperation on issues such as management model for municipal markets, in collaboration with the Municipal Institute of Markets of Barcelona.

And the managers of the San Martín de Donosti market also travelled to Barcelona to take a tour of several markets in the IMMB network, given that they were faced with the challenge of carrying out actions to improve and reform their market.

In addition, the Municipal Institute of Markets of Barcelona (IMMB) has been part, since 2018, of the World Union of Markets, an entity created in 2001 and made up of wholesale and retail food markets from several countries.
