There is a huge difference between Disney and Universal involvement with China.
Disney isn't "loved" in China like in America and other areas whereas Viacom/Universal have so many stragetic alliances already in place with many companies. (China has Nickelodeon whereas China won't allow a disney channel). Universal is already partnered with a lot of the big businesses and Wanda Group just bought out Legendary (you know the guys with a 5 year film deal with Universal and coproduced Jurassic World/Straight out of Compton). That makes them the most powerful entertainment company in China with owning AMC theatres and Australia's Hoyt theatres. Therefore most of the IPs being used in China are shared properties as a Chinese owed company which they will want even more success.
Disney was just the worst company to try to work in China as they have the smallest media presence of all the companies and the people have no connection with Disney films.
Also all of Universal's major films next year were also have partnerships with all of Chinese biggest companies (Alibaba, Tencent, Weibo) for promotion and marketing pre the announcement of a theme park so I think Universal was a bit more prepared than Disney.
