One of the best strategic outcome from the interests of China would be the shutting down of the terror-sponsoring Al-Jazeera.
Turkey's indignation can be understood because they were strange bed-fellows during the height of the Syrian Jihadist mercenary war. Lots of dirty laundries might be spilled around if Qatar fell under strict KSA-led regulations.
Turkey also has received massive investment from Qatar, which gave the country the required breathing space at a time Syrian war-originated terrorism as well as tensions with Russia shook Turkish economy by the roots.
Interestingly enough, Al Jazeera established a sister broadcasting station in Turkey, although I am not sure it is still on.
It's very sure that if there is going to be one country (or government) that will be greatly affected, that's Turkey, not Iran or Russia.
As for China, it will rightfully never get meddled in, but just macro manage from far away. I agree, however, with the Turkish member that, KSA would not be considered a poster boy of anti-terrorism, quite the contrary, their spew of hateful religious ideology is as dangerous as that of Qatar.
No wonder KSA has fallen from the top of the China's oil import partners.
