Lithuania issued such a call at an information meeting of EU foreign affairs ministers on Friday in Copenhagen.
"Head of the Lithuanian diplomacy called on the EU member states to speak with one voice on the irresponsible nuclear energy projects in Belarus and Kaliningrad region, violating international nuclear safety principles, standards and conventions," Lithuania's Ministry of Foreign Affairs said in a statement.
Ažubalis underlined that at a time of crisis "it's particularly important to preserve a united EU foreign policy based on solidarity and common values, ensure harmony and visibility of EU actions, and employ the European External Action Service."
According to the statement, the head of the Lithuanian Ministry of Foreign Affairs also voiced concern about an increase in religious violence in the world and called on the EU to more actively protect religious minorities subjected to acts of violence.
Belarus plans to build a nuclear power plant less than 50 kilometers away from the Lithuanian capital, and Russia also wants to build its own plant in Kaliningrad region near the Lithuanian border. Lithuania claims it has not received satisfactory information on the evaluation of the planned plants' environmental impact.
