Apple CEO Tim Cook opened Apple's new store in Shanghai drawing a large crowd on Thursday.
Some people queued up overnight, according to posts on Chinese social media.
Cook arrived in Shanghai on Wednesday, he said on his personal Weibo account.
Meanwhile, the US Department of Justice (DOJ) is preparing to sue Apple for allegedly violating antitrust laws by blocking rivals from accessing hardware and software features of its iPhone, Bloomberg News reported on Wednesday.
Taking action against Big Tech has been one of the few ideas that Democrats and Republicans have agreed on. During the Trump administration, which ended in 2021, the Justice Department and Federal Trade Commission (FTC) opened probes into Google, Facebook, Apple and Amazon.
A DOJ spokesperson and Apple did not immediately respond to Reuters requests for comment.
