Switzerland:-be a tax haven for the scum of the world ,which ensures large money(dollars/gold) inflows, which ensures the local currency appreciates in value, that lowers inflation.

Saudi Arabia:-be part of a oil cartel to profiteer from low global oil supply compared to global demand, which ensures large money(dollars) inflows, which ensures the local currency appreciates in value, that lowers inflation ,

and also buy discount Russian oil for domestic consumption and sell your own oil at market prices to others.

China:-lockdown entire cites when a single covid case is found and welding people's doors closed, and significantly eliminate the demand side factors that cause inflation but destroy your GDP growth rate in the process too

and also buy cheap Russian gas and oil.
