President Kersti Kaljulaid is hosting Latvian President Egils Levits on the island of Saaremaa Thursday. Lithuanian president Gitanas Nauseda was also due to attend, but has canceled due to unforeseen circumstances, the president's office said Thursday.
The Estonian and Latvian heads of state are meeting in Kuressaare, the island's capital.
Lauri Kuusing, President Kaljulaid's foreign adviser said last week that part of the meeting would take the form of a post mortem of the coronavirus emergency situation in all three countries and the benefits of mutual cooperation throughout.
"[The pandemic] has brought us even closer to each other, increased mutual trust and laid a foundation to discussing some other important questions such as energy and transport - where cooperation is unavoidable, beneficial to all and increases the security of the region," Kuusing said at the time, according to the president's office.
Regional security, cyber cooperation and climate change are also on the table.
The meeting is part of an annual tradition dating back to 1991 when the three Baltic States became independent; they take turns to host it – this year is Estonia's turn.
A welcome ceremony in central Kuressaare – which was picked to bolster domestic tourism in the aftermath of the pandemic – on June 25, will be followed by a tree-planting ceremony in the town's castle and a visit to the Kaali meteorite crater.
Tuesday and Wednesday were national holidays in Estonia, marking midsummer.
