On June 10, 2025, Portugal celebrates its National Day, also known as Dia de Portugal, de Camões e das Comunidades Portuguesas—a tribute to the nation’s rich history, cultural heritage, and the enduring legacy of Luís de Camões, Portugal’s most celebrated poet.

A Day of History and National Pride

Portugal National Day commemorates the death of Luís de Camões in 1580. Camões is revered for his literary masterpiece Os Lusíadas, which celebrates Portuguese maritime exploration and the Age of Discoveries. His works encapsulate the spirit of a nation that once led global navigation and exploration. Today, June 10 honors not only Camões but also Portuguese communities around the world and the country’s contributions to global culture, language, and diplomacy.

Portugal–Thailand Relations: 5 Centuries of Friendship

The relationship between Portugal and Thailand is one of the oldest between a Western and an Asian nation, dating back to 1511. Portugal was the first European country to establish formal contact with the Kingdom of Ayutthaya, the predecessor of modern Thailand. This historic friendship laid the foundation for centuries of peaceful relations, trade, and cultural exchange.

Diplomatic ties were formalized with the signing of the Treaty of Friendship and Commerce in 1820. Today, Portugal and Thailand enjoy strong bilateral relations, marked by frequent diplomatic exchanges and mutual support in multilateral forums such as the United Nations.

Economic Cooperation and Trade

Trade between Portugal and Thailand has grown steadily in recent years. In 2024, bilateral trade reached approximately €340 million, with Thailand exporting mainly electronics, auto parts, and agricultural products, while Portugal exported wine, cork, ceramics, and machinery. Thai investors are also showing increased interest in Portugal’s renewable energy and tourism sectors, while Portuguese companies see Thailand as a gateway to ASEAN markets.

Business delegations, supported by both governments and chambers of commerce, have intensified their cooperation in sectors such as clean energy, food processing, and sustainable development—areas aligned with both countries’ green economic priorities.

Cultural and Tourism Exchange

Cultural diplomacy remains a cornerstone of the Portugal–Thailand relationship. The Portuguese influence is still visible in Thailand through architecture, cuisine (such as foi thong and thong yod, adapted from Portuguese desserts), and religion (notably Catholicism, which was introduced through early Portuguese missionaries).

Events such as Portuguese film festivals, culinary showcases, and educational partnerships with Thai universities have kept the cultural bridge vibrant. Meanwhile, Thailand’s rich heritage and hospitality attract Portuguese tourists in growing numbers. In 2024, over 25,000 Portuguese citizens visited Thailand, drawn by its temples, cuisine, and natural beauty, while Thailand continues to be an emerging destination for Portuguese cultural enthusiasts and business travelers alike.
