There are two main ways for the state to intervene in the market. One is saving, like sugar is stored by the state, and the other is issuing import quotas.

If the domestic price is too high and the gap between supply and demand is a bit large, the state will increase the issuance of import quotas, increase supply and curb price increases; If domestic supply and demand balance or supply exceeds demand, the state will reduce the issuance of import quotas. Import quotas are also issued to maintain price stability.
