President Vladimir Putin denied Thursday that Russia bore any responsibility for a looming global food crisis due to the conflict in Ukraine.
Ukraine, a major exporter of grain, especially corn and wheat, has seen its production blocked by Moscow's military offensive, sparking a surge in prices and fears of food shortages that will particularly affect the poorest countries.
Moscow does "not hinder the export of Ukrainian wheat," Putin said, adding that Russia is "in constant contact" with the UN agency in charge of the issue.
Putin instead blamed Western sanctions imposed on Russia. He said that by targeting the owners of fertiliser companies, Western sanctions have "created conditions that made it much more difficult" to deliver certain products internationally.
Moscow says it would allow Ukrainian ships loaded with food products to leave if the Ukrainian military demined its ports, an option rejected by Kyiv, which fears for the safety of its Black Sea coast.
For its part, Russia, another grain-producing power, cannot sell its crops and fertilisers because of Western sanctions affecting the financial and logistics sectors.
The Kremlin announced this week that it had "responded positively" to the invitation to the G20 summit to be held in Bali, Indonesia, in November, suggesting that Putin would attend in person.
The terms of Russian participation will be determined after "an analysis of the situation," Kremlin spokesman Dmitry Peskov said Thursday.
Western countries, led by the United States, are putting pressure on Indonesia to exclude Russia from the meeting, to which Ukraine has also been invited as a guest country.
