Russia is continuing efforts to build a coalition to counterbalance the West, the Institute for the Study of War (ISW) reports.
The US-based thinktank noted that in recent months Russia had been pursuing bilateral relationships with Iran, North Korea, and China.
This month, Russian deputy foreign minister Andrei Rudenko met with Chinese special representative on Korean peninsula affairs Liu Xiaoming and accused the West of "bloc thinking".
Russia has also "notably been pursuing an intensified relationship with North Korea", the ISW added, and has received ballistic missiles and artillery ammunition from the country.
Russian ambassador to China Igor Morgulov additionally met with Chinese Xinhua News Agency Head Fu Hua to "discuss bilateral cooperation in the media sphere".
Also this month, Iranian President Ebrahim Raisi held a phone call with Vladimir Putin to discuss bilateral cooperation.
The ISW reports that Russia's "pursuit of a stronger political and diplomatic bilateral relationship" with Beijing, Iran and North Korea represents a type of "bloc thinking " which Mr Liu and Mr Rudenko accused the US and its allies of.
