There is only one university in Brunei, called Brunei University. It seems that there are few foreign students in China, and this school also teaches in English. As for the cost, it won't be much. I found it in Baidu. In 2007, the accommodation fee was 2592 yuan. Four-year tuition 14400 yuan. I don't even know where Brunei is upstairs. In any case, Brunei is a rich country that has made its fortune by oil, and it is adjacent to Malaysia. Its residents believe in Islam, but there are many China people there. Besides, I don't think it is recommended to go to this country. This country has a territorial dispute with China, and Brunei is a small country. It is not worth spending so much money to go to a non-English-speaking country, and it seems that many Brunei people are abroad.
