South Korea has released three Chinese fishermen following a fatal clash between their trawler and a South Korean patrol ship earlier this month.
Seoul says the incident happened in the Yellow Sea as coast guards tried to prevent Chinese boats from fishing illegally off South Korea's west coast.
It said the trawler intentionally struck the patrol ship to allow others to sail back into their waters - but the boat sank after the impact.
One fisherman died in the clash.
Four South Korean coast guards were wounded as the Chinese fishermen attacked them with metal bars.
The clash triggered a diplomatic stand-off between Beijing and Seoul. BBC News
