Russian Foreign Minister Sergei Lavrov was allegedly on a flight headed to Beijing Thursday, but the plane turned around midway and flew back toward Moscow, according to German newspaper Bild. 

The plane allegedly turned around while over Novosibirsk, a city in Siberia, according to Bild. Fox News Digital has been unable to independently verify the outlet’s report.

A tweet posted by the Ministry of Foreign Affairs of Russia on Thursday states Lavrov was holding a press conference just ahead of 1 p.m. Thursday local time. That would put Lavrov in Moscow at the time he was allegedly in the air. 

It is unclear if China refused to meet with a Russian official or if Russian President Vladimir Putin called him back to Russia, according to Bild. The plane's final destination is also unclear. 

A State Department spokesperson told Fox News they did not have information to share on the matter.

Chinese foreign minister Wang Yi touted the country’s friendship with Russia earlier this month and called Moscow the "most important strategic partner" to Beijing. China has also so far not condemned Russia’s invasion of Ukraine, but China's ambassador to Ukraine, Fan Xiangong, praised the nation earlier this week. 

"We will always respect your state, we will develop relations on the basis of equality and mutual benefit. We will respect the path chosen by Ukrainians, because this is the sovereign right of every nation," Fan told Lviv officials on Monday, according to the Lviv regional government.
