I think your addition to the headline is inaccurate. Guyuk Khan had the Mongol Empress Torgene’s Muslim supporters within the Mongol court executed, and his successor in China was Kublai Khan, who sent a Nestorian Christian monk to the West to propose an alliance between the Mongols (who by then were majority Buddhist with Christian and shamanist minorities) and the Christians against Islam.
Yes, I stand corrected.
