In a Lattvian-language video uploaded from the conference, Vejonis said Pence had discussed regional security with him and "how to react to the changing security situation in the region."
A key point expressed by Vejonis was that "Latvia and the Baltic states aren't just interested in taking help from the US but also in giving help to the US and other NATO partners in the fight against terrorism in various places around the world."
In talks with the Baltic presidents, Pence had underlined that the US "has been, is and will be a stable NATO partner," and that the alliance's Article 5 commitment was beyond doubt, "if military aggression occurred against any NATO member state," Vejonis added.
"The US is ready to fulfill all the commitments it has made," Vejonis concluded.
The talks at the conference will to some extent reassure the US' regional allies that President Donald Trump's earlier description of NATO as "obsolete" and suggestions that support for allies might depend upon financial contributions, will not necessarily mean a sea-change in US policy.
