After Japan announced plans to conduct a maritime survey in the East Sea, a Japanese patrol boat appeared near the Korea-controlled Dokdo islets last weekend.
In fact, as Eun Jung reports the presence of Japanese naval vessels has been increasing near Korean waters in recent years.

11 a.m. April 15th. Korean activists capture video footage of a naval vessel approaching a Korean passenger liner on the East Sea.

CIVIC ACTIVIST: "The vessel was approaching our ship at full speed. It was a Japanese naval vessel. I could see the word Japan Coast Guard clearly and also the Japanese flag."

The Korea Coast Guard confirmed a 195-ton Japanese patrol boat passed through Korea's Exclusive Economic Zone Saturday morning.
It added the disputed vessel did not violate Korea's territorial waters, but four Korean patrol ships were standing by in case it did.
This is the 18th time so far this year that a Japanese patrol boat has appeared near the Dokdo islets.
The Korea Coast Guard says more and more Japanese patrol boats have been venturing close to Korean territorial waters on the East Sea, 79 times in 2005 and 50 in 2004.
The types of vessels have grown larger some estimated as much as 3,500 tons.
Amid the growing emphasis on marine resources, disputes over Exclusive Economic Zones, or EEZs, are also rising globally.
An Exclusive Economic Zone is a seazone stretching 200 nautical miles from a country's coast, where it controls the undersea resources.
Korea and Japan have held discussions until 2000 seeking to agree on a clear delineation of their respective EEZs, but a conclusive accord has yet to be reached.
