BALTREG is annual meetings of the Latvian, Lithuanian and Estonian electronic communications and postal regulators on the most topical sector issues, providing in-depth information and proposals for daily work. 

In 2003, following the PUC’s initiative the first joint meeting of the regulators of the three Baltic States and Nordic Countries (NORDREG) took place addressing the aspects of regulation of electronic communications. These meetings take place depending on agendas.

The PUC participates in meetings organised by ITU depending on agenda including actively participating therein transferring experience in regulation of electronic communications to representatives of different regions on service quality, scarce resources, significance of regulators for market supervision, authorisation regime and others.

The PUC signed the Memorandum of Cooperation with the Ukrainian National Commission for the State Regulation of Communications and Informatization on February 19, 2010. Within the framework of the Memorandum, the PUC has regularly shared experience on transposition of the EU legal acts, service quality, scarce resources, markets and regulation thereof and others. The PUC’s participation in a Twinning project started in 2011 in consortium with Spanish and Swedish regulators has also furthered the achievement of the objectives of the Memorandum of Cooperation.
