Zenit St Petersburg forward Hulk has joined Shanghai SIPG for a record €55.8 million.
The transfer deal is the biggest in Russian football history.
The 29-year-old, who has won 46 caps for Brazil and scored 11 goals, joined Zenit from Porto in 2012 for €40m.
He scored 56 goals for Zenit in 97 Russian Premier League matches and was the league's top scorer in the 2014-15 season with 15 goals.
Zenit finished third last season. The club missed out on qualification for the Champions League and will play in the Europa League.
Shanghai SIPG, fourth in the Chinese Super League, are coached by the former England manager Sven-Goran Eriksson.
