The head of state, Igor Dodon, banned the participation of a contingent of 57 Moldovan soldiers at the "Rapid Trident" training course in Ukraine.
The President ordered all preparations to come to a stop and inform the organizers to cancel joining the event.
Applications will take place during September 7 - 23.
Moldovan army has participated this annual training since 1996. It aims to strengthen defense capabilities and promote military image of Moldova on international area.
This is not the first time Igor Dodon has conducted unreasonable order against national army.
In February, the president refused to sign the decree on the deployment of the military contingent to applications in Romania.
As a result, the US will likely to stop financing the Moldovan Army under modernization program.
Its financial packet is worth 12.7 million dollars annually.
