Amid a growing partnership between China and Russia, Mandarin has been growing in popularity across Russia as a foreign language of choice, a trend Putin said was due to developing contacts across economics, politics and society.

Putin, who speaks fluent German but has also taken lessons to improve his English, said that pupils should not forget the importance of English.

Russian, English, Tatar, German and Chechen are the most widely spoken languages in Russia, according to the 2022 census. While Mandarin is spoken far less, it has been growing swiftly in popularity in recent years as a foreign language.

English is the world's most spoken language with about 1.5 billion speakers, followed by Mandarin Chinese with about 1.1 billion speakers, and then Hindi, Spanish, Arabic, French, Bengali, Portuguese, Russian and Urdu, according to Ethnologue, a language research centre.
