Russian Deputy Prime Minister Dmitry Rogozin is expected in Moldova on August 21 amid tension over trade restrictions and the former Soviet republic's tilt toward Europe.
Moldova tightened ties with the European Union by signing an Association Agreement in June despite Russian opposition.
Moscow placed restrictions on Moldovan imports in July and plans to impose customs duties starting September 1.
Rogozin and Moldovan Deputy Prime Minister Adrian Candu are scheduled to discuss trade when they meet.
Rogozin is expected to spend a few days in Moldova and visit the breakaway, pro-Russian Transdniester region. He created a stir in May when he said his plane was barred from Romanian airspace after a Transdniester visit and vowed to take a strategic bomber next time.
Russia's annexation of Crimea and the conflict in eastern Ukraine have raised fears in Moldova that Moscow could have designs on Transniester.
