Update 4/28/20: Yes they have.
(Update: 7/11: No they haven’t)
Jagex is no longer Chinese owned. This news was first revealed back in the old era of January 2019, but this week China’s Fukong Interactive Entertainment announced that they will sell Jagex which it described as their major source of revenue. The goal of the sale is not to offload bad assets, but to pay off heavy debts that Fukong has incurred from nearly 60 lawsuits and arbitration cases filed against the company (Fukong, not Jagex).
As part of the sale, Jagex has been valued at approximately $530 million USD. Jagex’s revenues topped over $100 million USD last year which comprised 99.5% of Fukong’s revenue. Fukong’s plans post-Jagex involve developing mobile video games.
