Maybe the government are trying but keeping the inflation away may just be unavoidable. Some policies may sound good, but on implementation may not provide the required results.
For a country not to have inflation is not good, it is people that should know that they should not save money in fiat because government will always devalue it for their own benefit. It is not mandatory to have your money in fiat. You can invest it or use it for business. If a country do not want to have inflation, the economy of the country may collapse.
