Foreign Minister Yoshimasa Hayashi commended a recent visit by Cambodian leader Hun Sen to Myanmar, which was the first by a foreign leader since the military coup in February.

In a phone call with his counterpart Prak Sokhonn on Tuesday, Hayashi said he remained concerned about violence in Myanmar, and welcomed Cambodia’s positive efforts to resolve the situation, according to an emailed statement from the Foreign Ministry. Hun Sen’s trip resulted in progress toward a ceasefire with ethnic minority groups and enabling humanitarian support, Hayashi added.

While Japan has called on the junta to stop the violence and restore democracy, it wants to remain close to Myanmar as part of a strategy of countering China’s influence there and to also protect significant investments in industries ranging from consumer goods to banking. Military ties between Japan and Myanmar have remained strong.
