A senior NATO official says Russia would prefer to shock and intimidate rather than have a predictable relationship with the military alliance.

NATO Deputy Secretary-General Alexander Vershbow said Friday that the alliance would assess its relationship with Russia to find ways to "restore predictability and transparency," at NATO's summit in Warsaw next year.

Vershbow, a U.S. diplomat, said Russia appeared to be "more interested in shocking, surprising and intimidating than in calming and building confidence."

Touching on Romania's neighbor Moldova, which has a large Russian minority, Vershbow said NATO was helping the former Soviet republic with defense reforms and a strategic assessment of national security threats. It is also helping Moldova with cyber security and professional military education and training.

Moldova is a member of NATO's Partnership for Peace program.
