Earlier in the day, Latvia's Maris Kucinskis, Estonia's Taavi Roivas and Lithuania's Algirdas Butkevicius held a meeting in the Latvian capital of Riga. The heads of the government discussed a number of issues, including cooperation in the sphere of energy.
According to the Delfi news outlet, following the meeting the prime ministers formally reiterated their opposition to the construction of the pipeline.
The project is opposed by some EU member states, such as Poland and the Baltic states due to concerns over increased energy dependence on Russia. At the same time, Berlin reaffirmed its interest in the project in late 2015, saying that it would bring more benefits for EU members and provide energy safety and security to the 28-nation bloc.
