Unlike Grybauskaitė, presidents of Latvia and Estonia have accepted the invitation of Polish President Bronislaw Komorowski to come to the Polish capital.
"A visit to Warsaw is not on the agenda for next week," presidential adviser Daiva Ulbinaitė told BNS on Tuesday morning.
Later asked to specify the reasons behind the decision, the presidential aide said: "This is because preparations for the NATO summit in Chicago have already been discussed with the Polish president and the Latvian president, as well."
"No official invitation has been received, the president discussed the matter in a telephone conversation with the president of Poland," Ulbinaitė said.
Asked to comment on media reports about the possibility of Poland's revision of its participation in NATO air-policing mission in the Baltic states, she replied: "I can confirm that the president was notified about such diplomatic talks and has discussed the matter with the Polish president during his visit to Vilnius on 16 February."
After BNS specified the diplomatic conversations, Ulbinaitė said the conversations in question were "statements by Polish diplomats to Lithuanian diplomats that Poland could revise its stance on the air-policing mission in case we fail to address problems that national minorities are facing."
Spokespeople for presidents of Estonia and Latvia, Toomas Hendriko Ilves and Andris Berzins, have confirmed their participation in the meeting scheduled to take place in Warsaw next Tuesday.
"President Ilves considers it important for our region, in which Poland undoubtedly has a special role, to have a common view on security-related challenges in both the Baltic Sea region and more broadly," the Estonian president's spokesperson said.
The Latvian president's service has also confirmed that Berzins will be present at the 17 April meeting in Warsaw.
Relations between Lithuania and Poland have been tense lately, amid differences of opinion on the situation of national minorities.
