Lithuanian Minister of Foreign Affairs Linas Linkevičius says it will be a working meeting, aimed at continuing cooperation with US security officials following the resignation of former national security adviser Herbert McMaster in March.
"As you know, we had great contacts with former national security adviser McMaster, we had regular contact, we used to discuss his very specific steps and what we should do in bilateral relations, within the NATO context, and for the upcoming summit," Linkevičius told journalists after leaving for Washington.
"A new adviser has recently started working and we would like to renew all of this," he added.
The Baltic states want the United States to send troops for training more often and air defense systems in order to deter Russia.
Lithuania is also negotiating with Washington the establishment of a regional cyber security center in Lithuania's second-largest city of Kaunas.
