"The stress tests are only part of that whole big picture, because they don't cover such things as the reasons for the choice of the site and environmental requirements," Nerijus Aleksiejūnas told the Žinių Radijas radio station on Tuesday morning.
"The presence of a power plant near our border, close to Vilnius, is also a certain tool that can be used for Russia's geopolitical purposes. That's why it's not right to speak only about the stress tests. We take a much broader approach and see it as an issue of national security," he said.
The advisor expects Belarus to implement the recommendations in a timely manner.
"The final document will be published today or tomorrow, but we already see that there are shortcomings. They are clearly identified," Aleksiejūnas said.
"Our goal is to ensure, together with the European Commission, that there is a clear commitment by Belarus to implement these recommendations before the power plant can be launched," he added.
The stress tests were carried out by Atomproekt, a subsidiary of Russia's Rosatom, the Astravyets project's main contractor, in 2016 and were later reviewed by an international panel of experts set up by the European Commission and the European Nuclear Safety Regulators Group (ENSREG).
Lithuania, the main critic of the Astravyets plant under construction just 50 kilometers from Vilnius, last year declared the project a threat to national security, the environment and public health.
Minsk rejects the criticism, saying that it will ensure the highest safety standards at the Astravyets plant.
