Cambodia is planning to join the Madrid System for the International Registration of Marks by 2015, according to the relevant authorities. The Madrid System greatly simplifies the process for trademark owners to register their rights in multiple countries at a time.
To register one’s trademark in countries outside the Madrid System, as Cambodia currently is, you have to make a separate application with the national authority (in Cambodia that is the Department of Intellectual Property within the Ministry of Commerce). Once Cambodia joins the Madrid System, it will be much easier, quicker, and cheaper for Cambodians to protect their trademarks abroad, and for foreigners to protect theirs in Cambodia. This would be a good development for intellectual property in Cambodia.
