The methodology of the research used normative legal reasearch with political aspect. The result of the research shows that Indonesian Government has no responsibility upon the loss and damage of the countries whose the ships was sunk by Indonesian Government. The fact that Indonesia does not fulfill the requirements to be held responsible. Indonesia does not conduct internationally wrongful act nor violate international obligation. On the other hand, there is no regulation which regulates the prohibition on the sinking of foreign ship neither national law nor international law. Based on UNCLOS, the punishment cannot be imposed on the perpetrators who conduct illegal fishing in the Exclusive Economic Zone unless there is an agreement from both countries. Besides, the Article 69 paragraph 4 of Law Number 45 Year 2009 on the Amandment of Law Number 31 Year 2004 on Fisheries stated that Indonesia is allowed to sink the foreign ship based on the sufficient preliminary evidence.
