Lithuanian Prime Minister Saulius Skvernelis invited his Polish counterpart to visit Vilnius during their telephone conversation on Friday and Morawiecki accepted the invitation, the Lithuanian government said.
"The Polish premier accepted the invitation to visit Lithuania in March," Skvernelis' spokesman, Tomas Beržinskas, told BNS.
Morawiecki will likely take part in a meeting with the three Baltic prime ministers in Vilnius.
Poland had for a long time frozen top-level visits to Lithuania, accusing Vilnius over the situation of the Polish ethnic minority.
However, there has been an improvement in the past half a year. Marek Kuchcinski, the Marshal of the Sejm, the lower house of the Polish parliament, visited Vilnius in September and Polish President Andrzej Duda is expected to come to Lithuania for its centenary celebrations on February 16.
Observers say that Poland may seek support from Lithuania in a row with the European Union over its controversial judicial reform. Lithuania is interested in strong defense and energy ties with the neighboring country.
On 27 May Lithuanian government has allowed renewing more flights to Germany and the Netherlands .
