Japan has detected a suspected cargo transfer between a North Korean ship and a Belize-registered vessel, which apparently involves goods violating international sanctions imposed on North Korea, an official said on Thursday.
Tokyo reported the incident to the UN on Wednesday.
In the incident, captured by a Maritime Self-Defence Force airplane, both ships approached each other closely after exchanging light signals.
The Japanese government said it believes that the movement was "a possible transfer of goods violating the sanctions imposed on Pyongyang".
The incident was the latest in a series of incidents involving North Korean vessels allegedly violating the ban on supplies to Pyongyang imposed as a result of its repeated nuclear and missile tests.
Allegations in December that US satellites had detected Chinese ships selling crude oil to North Korean vessels at least 20 times since October, which China has denied, led Trump to express his disappointment on the social media.
