Japan's coast guard says it has arrested two Chinese boat skippers in separate cases of suspected illegal fishing in Japanese waters.
Officials say a 39-year-old skipper was arrested Tuesday for alleged coral poaching off the Goto islands near Kyushu.
They say the second skipper was arrested Wednesday near the Ogasawara islands, 600 miles (1,000 kilometers) south of Tokyo. They said Thursday that both allegedly ignored calls to stop for inspection, prompting a chase.
If convicted, the skippers could face up to six months in jail or a fine of up to 300,000 yen ($3,840).
The incidents aren't likely to spark disputes as they didn't occur in contested waters.
Officials say Chinese poaching in and around Japan is on the rise.
