Pope Francis is joined by Cardinal John Tong Hon, left, and Cardinal-elect Stephen Chow, both from Hong Kong, after presiding over a mass at the Steppe Arena in the Mongolian capital Ulaanbaatar, Sunday, Sept. 3, 2023. Francis is in Mongolia to minister to one of the world's smallest and newest Catholic communities. Neighboring China's crackdown on religious minorities has been a constant backdrop to the trip, even as the Vatican hopes to focus attention instead on Mongolia and its 1,450 Catholics. (AP Photo/Ng Han Guan)
