China, the Catholic news service AsiaNews says. He was 97.
Jin worked to improve tense relations between the Vatican-loyal underground church and China's officially-sanctioned Catholic church, which doesn't recognise papal authority to make bishops.
Vatican official Archbishop Savio Hon Tai-Fai on Saturday praised Jin's efforts to educate seminarians.
Jin, who died on Saturday, was consecrated a bishop in 1985 without papal approval but later reconciled with the Vatican.
He was first arrested in 1955 and spent a total of 18 years in prison and nine years in re-education camps.
In continuing tensions, Chinese authorities revoked the title of Jin's choice for successor, Auxiliary Bishop Thaddeus Ma Daquin, and confined him to a seminary after he withdrew from China's official body overseeing the church.
