Information about this appeared in the Telegram channel of the Russian diplomatic mission.
"We still have not received an official invitation from Washington," the ambassador said.
According to him, Moscow expects that Washington will ensure equal access for all delegations and the issuance of visas.
Earlier, the United States conveyed to Russia through bilateral channels that Washington was not going to invite a number of leaders, including Russian President Vladimir Putin, to the APEC summit in San Francisco.
Also, Russian Foreign Ministry spokeswoman Maria Zakharova said that Moscow insists that the meaning of APEC's work is not distorted.
