It has been Turkey's traditional policy to intervene in others' internal affairs based on ethnic affiliation. This has been witnessed in post-Soviet polities, for instance, albeit with checkered success.
With the latest Islamist AKP government, the ethno-diplomacy was devolved/regressed into ethno-religio sectarian diplomacy.
Syrian War exacerbated the situation.
Turkey has actively supported the recruitment, training and transfer of Uighur jihadists into Syria, along with many others.
This is a direct national security threat to and a breach of China's sovereignty.
This is, in the long run, a threat to the entire Central Asia and South Asia, including our ally Pakistan.
Out of historical wisdom and strategic foresight, Pakistan maintained a balanced approach and advised Turkey on its Syrian policy. Pakistan refrained from intervening in Syria and was rightfully absent from Saudi-led Islam Army.
Turkey's position on Syria has not changed till today. The attempted coup has not changed anything. It was/is an internal fight between two shades of a similar Islamist faction on who would take over the traditionally secular state and change its very DNA to its liking.
Turkey's presence in China as a G20 member has not changed anything, as well. China is always a keen economic actor; its economic cooperation cannot be mistaken for strategic cooperation or trust.
Turkey harbors Uighur terrorist organizations that are engaged in anti-China activities, from soft jihadist propaganda to hard training.
We know by fact that there are Uighur (and Chechnyan) fighters in terrorists groups directly created and supplied by Turkey. It is impossible that such a dangerous situation would allow for any Eurasian political area being formed in West Asia and the Middle East.
Strategically impossible even if we wanted it.
The emerging Eurasia is basically composed of the OBOR's northern corridor which involves China, Mongolia, Pakistan, Central Asia,. Eastern and Western Europe. The investment, actualized rail and highway connections, and established SEZs (4 of 20 are in Russia, for example) all indicate that emerging Eurasianism is based on China-Russia strategic collaboration as it overarching framework.
It has nothing to do with Turkey.
I think China does not care Turkey stays in NATO, or destroys all the bridges with the West. So far, destroying bridges with the West has resulted in alliances made with Qatar, Saudi Arabia and Israel. It means nothing for China.
Emerging Eurasianism is not anti-West; but it is an alternative order making that endangers Western supremacy, which might be viewed as anti-West. But, in its essence, it is not anti-West. There are more than 30 Western countries in the AIIB.
China's is strategic-minded and practical. my friend, as you know very deeply and on the historical-philosophical level.
What China needs to see is simply the end of political and civil support and endorsement of terrorists that harbor ill intention against China.
