Your question is wrong in itself. State-owned enterprises and central enterprises are not juxtaposed concepts. State-owned enterprises are state-owned enterprises, and the so-called central enterprises are state-owned enterprises owned by the central government, so central enterprises are a kind of state-owned enterprises. The concept corresponding to central enterprises is local state-owned enterprises. So central enterprises are also state-owned enterprises.
Go back to your question itself. China Cotton Group was originally affiliated to the Ministry of Economic Relations and Trade, and was later placed under the General Supply and Marketing Association of China. So it can be regarded as a central enterprise, and of course it is also a state-owned enterprise.
