YANGON, April 30 (Xinhua) -- Myanmar's military announced late Tuesday to extend the suspension period of all its military action against armed groups in five military command regions for two months, according to an announcement of the Office of the Commander-in-Chief of the Defense Services.

The suspension period was set to extend until June 30 this year, the announcement said.

The move came after the request proposed by three forces -- Kachin Independence Army (KIA), Ta'ang National Liberation Army (TNLA) and Myanmar National Democratic Alliance Army (MNDAA), in order to support negotiations with those remaining non-ceasefire signatory armed groups to sign the Nationwide Cease Fire Accord (NCA).

During the period, all military actions will be suspended in the northern, northeastern, eastern, middle-eastern and triangle military command areas.

Myanmar's military released the announcement of its non-operation period in December last year, setting to last until April 30, 2019.

So far, 10 ethnic armed groups have signed the NCA with the government since it was initiated in October 2015 and the 21st Century Panglong Peace Conferences were held three times during the incumbent government in August 2016, May 2017 and July 2018 respectively.

There remains mainly seven Northern Alliance armed groups which have not yet signed the NCA.
