China-focused ETFs are becoming an unlikely play on a global oil shock, offering investors a chance to invest in a country that may be better protected from energy disruptions from the Strait of Hormuz than the rest of the world.

China's strategic reserves, estimated at 1.2 billion barrels as of January, provide a protection against any potential oil crunch. However, recent economic indicators also show a positive outlook for the country's domestic growth.
