The document was signed in Namur, Belgium by Jandrokovic and by the Minister-President of Wallonia, Rudy Demott, and the Secretary of State of the Brussels-Capital Region, responsible for mobility, the civil service, equal opportunities and administrative simplification, Emir Kir.
According to a press release from the Croatian Foreign Ministry, Jandrokovic expressed satisfaction with the agreement which he said would give a framework for strengthening friendly relations and bilateral cooperation between Croatia and the Walloon Region, the Francophone Community and the Brussels - Capital Region.
He noted that Croatia and the Walloon Region had already developed cooperation such as the cooperation between the Croatian Chamber of Commerce and the Walloon Export and Foreign Investment Agency.
The minister also spoke about the importance of studying the French language in Croatian schools and universities.
A joint standing commission, that will hold its first meeting in Wallonia next year, will be in charge of implementing the agreement.
