A statement said the Vatican learned with "surprise and regret" that the bishop of another district had been installed as auxiliary, or assistant, bishop in Jiangxi.The unauthorized installation appeared to be one of the most serious violations of a 2018 agreement between the Vatican and Beijing on the appointment of bishops.AsiaNews, a Catholic news agency, said Peng was secretly ordained a bishop with papal approval in 2014, four years before the accord, and spent six months under arrest at the time.The Vatican statement came a day after a Hong Kong court found Zen and five others guilty of failing to register a now-disbanded fund for pro-democracy protesters.Only six new bishops have been appointed since the deal was struck, which its opponents say proves it is not producing the desired effects."
