This was reported by the Permanent Mission of Russia to the OSCE on Twitter.

“They suggested studying the initiative of Russian President Vladimir V. Putin to create“ green corridors ”free of trade wars and sanctions for the unhindered supply of medicines, food, equipment and technologies for protection against coronavirus to everyone in need,” said Permanent Representative Alexander Lukashevich.

March 26, Putin called for the creation of sanctions-free "green corridors" and proposed a moratorium on restrictions that would make it difficult for countries to supply essential goods.
