3.4.1 Overview of main structures and trendsInternational cultural co-operation has mainly focused on the promotion of Portuguese language and culture. Hence the extensive co-operation with countries whose official language is Portuguese, through both the Camões Institute and international platforms such as the Community of Portuguese-Speaking Countries (Comunidade de Países de Língua Portuguesa - CPLP), which includes Portugal, Brazil, Angola, Mozambique, Cabo Verde, Guiné-Bissau, S. Tomé and Príncipe and East Timor). In November 2008 this organisation issued a Declaration following an Extraordinary Meeting of CPLP Education and Culture ministers. The objective: to encourage the appreciation and use of the Portuguese language internationally, starting out by appealing to member states to implement the Spelling Agreement signed in Lisbon in December 1990. Portugal began applying the Spelling Agreement in 2010, the aim of which is to encourage the use of the Portuguese language internationally and implement a common set of rules in the signing countries
Portuguese language and culture are also disseminated by means of television and radio. Television: RTP International (RTP-I, since 1992) and RTP Africa (RTP-A, since 1998), broadcast in all Portuguese-speaking African countries except Angola. Radio: RDP Africa, the broadcaster of Portuguese Radio to lusophone African countries.
International cultural cooperation also includes the exhibition of works of art in other countries (participation in festivals, biennial exhibitions and other international fairs), as well as major events organised in Portugal itself - like Porto 2001 Capital of Culture, and Guimarães European Capital of Culture in 2012.
