Through mid-April and into May, the already tense relations between Seoul and Tokyo moved closer to the breaking point when Japan began to implement its plan to conduct a maritime survey around the islets of Dokdo/Takeshima, which are controlled by South Korea and are claimed as sovereign territory by both states.

In response to the dispatch of Japanese research vessels, Seoul sent twenty gunboats to Dokdo/Takeshima in order to prevent the survey. As the two sides edged toward confrontation, rhetoric escalated and nationalist public opinion was mobilized, particularly in South Korea. A round of diplomacy resulted in a temporary stand-down, but the patchwork agreement was followed by a hardening of positions that does not bode well for a permanent solution to the dispute.
