The occasion was the second Russia-Mongolia regional forum, 14 and 15 September at the Blue Sky hotel, with more than 220 participants from 14 regions of the two countries; the first was in Irkutsk on 1 and 2 December 2025. Overchuk led the Russian delegation and spoke after talks with first deputy prime minister and economy minister Zh. Enkhbayar. On the Mongolian side the forum was opened by roads and transport minister B. Delgersaikhan, and its first panel was on transport corridors and border checkpoints.
The agreement was signed in Minsk on 27 June 2025 and ratified by May. It covers about 90% of the two sides’ trade, runs 3 years and renews automatically for another 3. On the Commission’s arithmetic, quoted by Interfax at entry into force, the average duty Russian goods meet on the Mongolian market fell from 6% to 0.2%, worth about 8 billion roubles a year to Russian business, and mutual trade grew by a third in the first quarter of 2026 before the tariffs moved. Mongolia’s list in the same account is meat, cashmere and textiles.
The product the Mongolian state rations is outside it.
‘We want to make it so that after 3 years of our temporary agreement we can speak of its implementation, and speak of moving to a permanent, broad, full-format free-trade agreement between the EAEU and Mongolia,’ Overchuk said. On the forums themselves he was shorter: they must continue, and Moscow gives the question very great attention.
Moscow’s offer is market access for what Russia has to sell, on a clock that runs to July 2029. The product the Mongolian state rations is outside it. Petrol and diesel do not appear on the list Interfax printed at entry into force, and Mongolia has zero-rated fuel imports on its own account until 1 February 2027, so a tariff schedule has nothing to add on the one Russian export Ulaanbaatar queues for. That product moves on the fuel headquarters’ allocations and Rosneft’s commercial track: in August the headquarters ordered 74,780 tonnes of AI-92 and received 68,502, 8.4% short, while diesel came in full at 158,530 tonnes, and the regulated pump price for ordinary AI-92 stood at ₮3,040 a litre from mid-August.
Beijing’s offer, put in numbers by the industry ministry on 10 September, is tonnage: 10,000 tonnes of petrol, 4,000 of jet fuel and 3,000 of diesel for September, a request for 5,000 more petrol and 20,000 to 30,000 of diesel, and a proposed 20-year partnership with a price formula the ministry’s text described as transparent, fair and understandable. Moscow’s is an average duty of 0.2% on its list and a promise about 2029.
What changes next has two dates. The Khural’s autumn session opens on Tuesday with the budget rewrite that funds fuel and food reserves; the move Overchuk describes waits for the 3-year term, which runs to July 2029. Between them sits a forum agenda of transport corridors, border posts, sport and medicine, and a Russian minister’s promise to keep holding forums.
The offer's annex lists 367 tariff lines. Whether petroleum products are among them, and at what rate, is unclear.
