SPR?

The United States has a Stragegic Petroleum Reserve that is intended to be used in the case of a supply disruption. China also has an SPR, but it's a different commodity:

The crisis over pork prices in China, like the jolt many Americans feel when gasoline prices jump, offers one example of how prices can suddenly soar. The Chinese government is struggling to cope — including deliberating whether to sell a snuffling, smelly strategic reserve of hundreds of thousands of live pigs kept at special subsidized farms for precisely the shortage the country is now facing.

Hmmmmm....Strategic Pig Reserve?
