"Clearly we need to broaden the concept of our security to include internal security and internal systems," Reirs said.
"We each have our own view of the border between Latvia and the Russian Federation, which is the European Union's eastern border - so it's different from the border between France and Spain for example," Reirs said.
"The definition [of security] needs to be broadened and both myself an the Prime Minister are talking to the European Commission to make sure they understand these concerns, for example about the strengthening of the border, increasing the number of personnel and so forth."
"This all concerns security and security does not just depend upon the defense budget," Reirs said.
"Seeing what's happened in Ukraine and those potential threats, it's of great importance to make sure these [internal security] structures are taken care of," he added.
Latvia will fulfill its commitment to spend 2% of GDP on defense by 2018, Reirs asserted, despite the fact that budget revenues are currently lower than expected.
