TOKYO/SEOUL (Reuters) - Japanese Defence Minister Takeshi Iwaya “strongly protested” to South Korea on Friday after a South Korean destroyer allegedly locked its targeting radar on a Japanese surveillance plane.

Iwaya, speaking to reporters at his ministry, described the action as “extremely dangerous that could cause an unexpected situation”.

The incident came at a time when greater coordination is called for between the two Asian neighbors to tackle issues including North Korea’s nuclear and missile programs, maritime security and natural disasters, he said.

“It’s extremely regrettable that the incident of this time happened,” Iwaya said. “We will urge South Korea to prevent a recurrence.”
