The Lithuanian Defense Ministry's officials in say that the status will allow increasing the salaries of instructors serving in Ukraine by around 10 percent and will facilitate cooperation with US and Canadian instructors working in that country.
They say that the parliament's decision will not pave the way for Lithuanian troops to directly participate in combat operations.
The resolution, which was passed with 103 votes in favor, none against and no abstentions, will take effect on July 1.
Lithuania has been sending its instructors to Ukraine since 2015. Around 30 Lithuanian troops are currently serving in Ukraine. The Seimas' decision allows sending up to 60 servicemen and civilians to the country.
The conflict between Ukrainian troops and Russia-backed separatists in the eastern part of the country began in the spring of 2014, around a month after Russia annexed the Crimean peninsula.
