SEOUL (REUTERS) - South Korea said on Tuesday (Oct 11) it would use greater force, including firearms, against Chinese boats fishing illegally in its waters and summoned China's ambassador to protest against a clash between a Chinese vessel and a coast guard boat.
South Korean coast guard vessels regularly chase Chinese boats for fishing illegally off its coast, at times resulting in violent confrontations.
The disputes are an irritant in relations between China and US ally South Korea, even as their economic relations grow close and they share concerns about North Korea's nuclear weapons and missile programmes.
South Korea's coast guard said on Tuesday that its officers would be authorised to use firearms, including handguns and onboard cannon, against illegal Chinese fishing vessels if deemed threatening.
"We will actively respond to Chinese fishing boats that obstruct justice by using all possible means if needed such as directly hitting and gaining control of those Chinese fishing boats, as well as firing common weapons," Mr Lee Choon Jae, the deputy chief of South Korea's coast guard, told a news conference.
South Korea's Ministry of Public Safety and Security, which oversees the coast guard, said one of its patrol boats sank last week during an operation to crack down on a group of Chinese vessels fishing illegally off the Korean peninsula's west coast.
It said the patrol boat was rammed by one of the Chinese vessels. No injuries were reported.
The Chinese vessel fled the scene and returned to its home port, the South Korean coast guard said.
Mr Qiu Guohong, China's ambassador to South Korea, did not comment to reporters as he arrived at the Foreign Ministry.
A South Korean deputy foreign minister told the Chinese Ambassador that the incident was "a challenge to public power", said Mr Cho June Hyuck, a spokesman for the ministry.
Three Chinese fishermen were killed last month in a fire that broke out on their boat when a South Korean coast guard crew trying to apprehend them for illegal fishing threw flash grenades into a room in which they were hiding, according to a South Korean official.
In June, South Korea and the United Nations Command, which oversees the Korean War armistice, launched a joint operation to keep Chinese fishing vessels from operating illegally off South Korea's west coast.
