Poland’s Mateusz Morawiecki and Lithuanian Prime Minister Saulius Skvernelis were also to discuss bilateral relations, security and defence, and the European Union’s next multi-year budget.
The talks were being held in the border town of Budzisko on the day that Lithuania lifts controls at its crossings with Poland.
Poland, meanwhile, is to reopen its borders with its EU neighbours including Lithuania on Saturday as it eases a coronavirus lockdown.
Poland temporarily closed its borders to non-residents on March 15 in a bid to curb the spread of the coronavirus epidemic.
A total of 28,201 people have tested positive for the COVID-19 disease in Poland, with 1,215 deaths from the coronavirus so far, officials said on Thursday.
