International travel can allow people to exchange ideas, gain valuable life experiences, and gain greater wisdom that can only be gained during the course of their travel. However, despite the possible benefits of international travel, it can potentially harm countries that are strongly attached to their own culture. In this case, Brunei Darussalam, as a country, strongly emphasizes the philosophy of the Malay Islamic monarchy. Since the nation's philosophy plays a vital role in Brunei's way of life, the exchange of views from other countries can pose a threat to its traditional cultures, particularly in the areas of language, Malay customs and environment. First of all, with international travel, people inevitably have to use international languages ​​to communicate, which affects the use of our native and second languages. One of the many threats arising from international travel stems from the need to communicate with foreigners. It is inevitable that people make use of international languages ​​and this indirectly affects our mother tongue.

Although Malay dominates neighboring ASEAN countries, it has yet to be recognized in other places.

It is up to our country's preparedness to overcome the problems and try to acquire as many benefits as possible by incorporating ideas gained from international travel into its national development strategies to satisfy all stakeholders and improve the condition of Brunei. Otherwise, not only has Brunei lost its culture, but future generations will also not be able to experience the similar cultures that our ancestors experienced decades ago..
