Southeast Asian countries: Interesting facts & travel highlights

1. Overview of Southeast Asian countries

1.1. Geography and climate

Southeast Asia is a region located between the Indian Ocean and Pacific Ocean, with many of the world’s key shipping routes passing through it. The region is made up of 11 countries divided into two main parts.

1.2. History and culture

Southeast Asian countries have a rich history shaped by ancient kingdoms, colonization, and modernization. Powerful empires such as the Khmer, Srivijaya, and Majapahit left behind iconic landmarks like Cambodia’s Angkor Wat, Indonesia’s Borobudur, and Myanmar’s Bagan. Over the centuries, Southeast Asia embraced major religions including Hinduism, Buddhism, Islam, and Christianity. European powers such as Britain, Portugal, France, and Spain used to colonize different parts of the region. By the 20th century, however, most Southeast Asian countries had gained their independence.

Today, Southeast Asia is one of the most culturally diverse regions in the world. People speak many different languages, such as Thai, Vietnamese, Malay, Tagalog, Burmese, and Khmer. English is also becoming more widely used, especially in education and business. The region is home to various ethnic groups, including Malays, Thais, Burmese, Khmer, Chinese, and indigenous communities, each with their own traditions, cuisine, clothing, and festivals. With its deep history and vibrant culture, Southeast Asia travel offers a truly colorful and unforgettable experience.
