Now a new plant near Lipetsk, a city 450 km (280 miles) south of Moscow, using potatoes grown on local farms will supply frozen fries to the chain of 651 outlets across Russia under a long-term contract, raising the share of the chain’s locally sourced products to 98 percent.

“This gives us the possibility to continue our development in a more stable way,” the chairman said. “It minimizes the risks connected to customs and administrative decisions, and guarantees stable, predictable prices in rubles.”

The plant, worth 8.7 billion rubles ($140 million), was built jointly by Russian agricultural group Belaya Dacha and the Netherlands-based Lamb Weston Meijer, both long-time partners of McDonald’s.

The factory has capacity to process 200,000 tons of potatoes a year, washing, cutting and freezing the vegetables.

The ruble has recovered some ground as the price of oil, a major revenue earner for Russia, has risen from a low in 2016.

Russia’s response to Western sanctions included a 2014 ban on a range of Western food imports.

“Sanctions as well as counter sanctions not only affect our company but the whole industry and the economy,” said Khasbulatov, whose firm has 50,000 Russian employees and more than 160 domestic suppliers.

“But in any case we continue our development, continue to build new restaurants and modernize existing ones,” he said, adding that firm opened 41 restaurants in Russia in 2017.
