The 2035 strategy, which has been sent to the government for discussion, would cost more than 4.4 trillion roubles ($70 billion) in funds drawn from private investors, loans and government financing, the ministry said in a statement.

The proposal to ramp up investment in the sector comes as state-controlled VTB, Russia's second-largest bank, has been buying grain export infrastructure assets.

Russian grain supplies could play a key role in President Vladimir Putin's plan, announced a year ago, to increase the country's exports of agricultural products to $45 billion by 2024. The Agriculture Ministry is in charge of that initiative.

Russia, the world's largest wheat exporter, would produce 140 million tonnes of grain annually by 2035 in the draft strategy's base-case scenario, while exporting 55.9 million tonnes, the ministry said.

In an optimistic scenario, the crop could rise to 150.3 million tonnes with exports totalling 63.6 million tonnes, it said, considerably higher than forecasts for this year.

This year, the grain crop will total 118 million tonnes with exports for the 2019/2020 marketing season at 45 million tonnes, according to the ministry.

The strategy prioritises increasing grain production, improving its quality, increasing domestic demand and developing infrastructure and logistics, the ministry said.

The plan proposed increasing the capacity of port elevators, transloading and other infrastructure facilities, while raising grain storage capacity to 167.4 million tonnes by 2035 from 156.9 million tonnes now.

The combined measures should allow infrastructure costs on the price of grain to fall 10% by 2035, the ministry said.

VTB owns stakes in two grain export terminals in the Black Sea port of Novorossiisk and has said it is in talks to buy a stake in another terminal in the Black Sea port of Taman.

Other big names in Russian grain trading include Russian firm RIF and global trade giant Glencore, as well as Aston.
