According to information available to BNS, the meeting is planned for next Wednesday, 18 July.
Diplomats said Kubilius had received a personal invitation from his Polish counterpart awhile ago to watch the FIFA Euro 2012, however, the visit had to be postponed due to important votes on energy bills.
The Warsaw meeting is planned to address economic relations between Lithuania and Poland, common interests in the European Union (EU) and the Eastern Neighborhood.
Lithuanian-Polish relations have lately been tense over the differences of opinions regarding the situation of national minorities.
Lithuanian Minister of Foreign Affairs Audronius Ažubalis told BNS on Friday he sees the visit as a totally positive thing.
"Contacts with neighbors are a good thing, and prime ministerial contacts are always a good thing as they are government heads who make a lot of practical decisions. I see it as only a positive thing. I also see positive things as regards the letter of congratulation by Polish President Bronislaw Komorovski, read out by the Polish intelligence chief here," the minister said.
"All that is good and I would only say that we are always open, we don’t need to close up, Lithuania has never been closed-up. Lithuania is always open to relations with Poland," Ažubalis said.
Earlier this week, Polish Minister of Foreign Affairs Radoslaw Sikorski's said Warsaw is ready for a new opening in relations with Lithuania but it must include meeting by Lithuania of obligations set out in the Polish-Lithuanian Treaty on Friendly Relations.
Lithuanian President Dalia Grybauskaitė has said recently Lithuanian-Polish working relations are very good, and political cooperation might wait amid disagreements over mutual concessions.
"Our relations, especially working relations, i.e., in the areas of economy, commerce, the implementation of common projects, are very good, and I would even say, more effective than before when top political relations were better," the president told the IQ magazine.
Earliest this week, head of Poland's National Security Bureau, Stanislaw Koziej, said during his visit to Lithuania that countries should not have any gaps in their relations.
"We should not have any political obstacles and we should not have any gap and interruption in our relations because such interruption is something worst. It is easy to cut off, interrupt relations, but it is more difficult to reinstate dialog ant cooperation later," Koziej told journalists in Vilnius on Wednesday.
