More countries joining the export ban might drive Bulgaria to take measures

As Russia has imposed a quota of 7 MMT for grain exports, there's an expectation that Bulgaria would follow the example by restricting or banning grain and pulse exports.
If there is an increasingly high demand for Bulgarian grains and pulses then the Bulgarian government might want to restrict the outbound foreign trade in order to secure the supply and maintain accessible domestic prices.
The main worry of exporters is not regulations that restrict exports of food commodities but it is the period of duration imposed by governments.
