China has mostly had amicable relations with Iran and a more hostile relationship with Turkey due to Turkish support for Uyghurs and East Turkestan independence movement. Iran is one of the signators defending China's re-education camps while anti-Chinese sentiment has sometimes been expressed by the Turkish leadership.[82][83] China and Iran have also signed a 25-year strategic pact, which was seen by Ankara as a threat for Turkey's ambitions.[84]
