Russia will supply 12 Su-30MK2 fighters and associated weapons for them to Vietnam, reports Interfax citing a source close to the deal.
The deal is worth approximately $1 billion, and the delivery is scheduled between 2011 and 2012, the source said.
Russia and Vietnam have already signed two major arms deals recently. In 2009, Moscow agreed to sell 8 Su-30MK2s to the Asian country and to construct six Kilo diesel submarines for the Vietnamese Navy.
No official comment on the information has been issued so far.
