Petrodollars have dominated the global energy markets for more than 40 years. But now, China is looking to change that by replacing the word dollars for yuan.

Nations, of course, have tried this before since the system was set up by former US Secretary of State Henry Kissinger in tandem with the House of Saud back in 1974

Vast populations across the Middle East and Northern Africa quickly felt the consequences when Iraq's Saddam Hussein decided to sell oil in euros. Then there was Libya's Muammar Gaddafi's pan-African gold dinar blueprint, which failed to create a splash in an oil barrel.

Fast forward 25 years and China is making a move to break the United States petrodollar stranglehold. The plan is to set up oil-futures trading in the yuan, which will be fully convertible into gold on the Shanghai and Hong Kong foreign exchange markets.
