According to the Office of the President, security and economic cooperation will be on the agenda for the meeting between the four heads of state.

"This meeting during the 100th anniversaries of our independence once again reaffirms the Baltic states' and U.S.' special bond and good cooperation," said Foreign Policy Adviser to the President Lauri Kuusing, recalling that the U.S. never de jure recognized the Soviet occupation of Estonia, Latvia and Lithuania.

"Our cooperation in the security field is very good, and all four countries are dedicating at least two percent of their [respective] GDPs to defense spending in 2018," Kuusing noted. "At the same time, there is mutual interest in increasing business contacts and intensifying economic relations, and a business forum will also take place in Washington on the sidelines of the meeting between the heads of state."

Kaljulaid and Trump most recently met in Warsaw last July. Last year, Vice President of the United States Mike Pence and Speaker of the U.S. House of Representatives Paul Ryan (R-Wis.) also visited Tallinn together with their delegations.
