Japanese Foreign Minister Hayashi Yoshimasa says his country is seriously concerned about the further extension of the state of emergency in Myanmar.

Hayashi issued a comment after Myanmar's state media reported the extension on Wednesday.

He said the country's military has been failing to work for political progress, such as the release of all of detained people, including Aung San Suu Kyi.

Hayashi said Japan again strongly condemns the situation, in which many casualties have occurred, despite repeated calls by the international community for an end to the violence.

The minister urged all parties concerned to refrain from violence and make efforts for a peaceful resolution to restore peace and stability in Myanmar.

He added that Japan will continue providing humanitarian support to people in Myanmar.
