Portugal-Bulgaria Bilateral Relations

Diplomatic relations between Portugal and Bulgaria began in 1878, after the liberation of Bulgaria from the rule of the Ottoman Empire. The first contacts between the two countries took place in the framework of numerous conferences and signing of international treaties. In the area of trade relations, on 4 July 1910,  the Agreement on Commerce and Navigation was concluded. In the field of political and diplomatic relations, on 27 October 1919, a Treaty of Peace was signed.

After the revolution in 1974, in Portugal, a new stage in the development of Luso-Bulgarian diplomatic relations began, in which diplomatic, economic and political contacts were strengthened. The Protocol on the Establishment of Diplomatic Relations between Portugal and Bulgaria was signed on 26 June 1974 in Paris with the aim of promoting cooperation and the consolidation of peace and international security. During this year, relations between the two countries were established at the level of Embassies in their capitals.

In order to promote economic relations between the two countries, in 1975, a Long-term Trade Agreement was signed, which established a Joint Luso-Bulgarian Committee for Economic Affairs of common interest.

During this year, a "Portugal-Bulgaria" Friendship Association was also created which promoted cultural dialogue between the two countries and aimed at giving a greater dimension to the promotion of Bulgarian history, science and culture among Portuguese.

The Agreement on Economic, Industrial, Scientific and Technological Cooperation was signed in Lisbon on 23 October 1975, in which cooperation in the field of shipbuilding, electronics industry, tobacco industry and others was agreed on.

During this year, other bilateral agreements were signed, such as the Agreement on Air Transport and the Agreement on Commercial Navigation.

With the purpose of promoting cultural and scientific relations through the exchange of knowledge in the field of culture, education, art and others, on 7 May 1976 the Agreement on Cultural Cooperation was signed and in the same year, the Convention for the Abolition of Visas was also celebrated. Between 1978 and 1979, the Agreement on Cooperation in the Field of Tourism and the Plan for the Exchange of Science, Education and Culture were signed.

In 1979, in Sofia, an agreement on International Road Transport of People and Goods was signed and, in 1995, an Agreement to Avoid Double Taxation was signed.

A new stage in Luso-Bulgarian relations began after 1989, when Bulgaria became part of the global economic space and expressed interest in the European institutions. The Bulgarian authorities expressed an interest namely in learning about the experience of Portugal's transition to democracy and the market economy. Throughout the years 1991-1993, several bilateral visits took place, resulting in various initiatives in the political, economic, commercial and cultural areas.

In March 1998, the first meeting of the Association of Luso-Speakers in Bulgaria - ALFB was held, with the mission of promoting Bulgarian-Portuguese relations, of disseminating ​​Portuguese cultural events and of providing support to citizens who wanted to study Portuguese. The following year, in Lisbon, a Luso-Bulgarian Association for Culture, Development and Science (ALB) was created, which provided the development and promotion of cultural, scientific and social relations between private entities in both countries.

A Cooperation Agreement in the Field of Tourism was signed in 1999. In 2002, an Agreement on the Reciprocal Recruitment of National Respectives to Prevent Illegal Emigration and to Develop Relations in the Field of Employment was signed.

On 6 November 2013 the Camões Centre was inaugurated at the Portuguese Embassy. This centre aims to implement the policy of promotion of the Portuguese language and culture in Bulgaria, covering the management of the Portuguese teaching network and the organization of cultural activities.

On 16 June 2015, during a visit of the President of the Portuguese Republic, and in the presence of the President of the Republic of Bulgaria, the Portuguese-Bulgarian Chamber of Commerce and Industry was founded, with the main goal of promoting bilateral economic relations between the two countries.
