BAGHDAD (Dispatches) – The 2003 invasion of Iraq was widely condemned as a war for oil. Two decades later, the companies most active in Iraqi fields are not American or British – they are Chinese.
If the aim was to hand Iraqi oil to U.S. and British firms, the result is strikingly paradoxical. Shell left Majnoon in 2018. ExxonMobil exited West Qurna-1 and handed the lead role to PetroChina in 2024. BP and PetroChina transferred their interests in Rumaila to a joint venture. In each case, Chinese firms filled the space western majors vacated.
The pattern is not limited to legacy fields. In Iraq’s May 2024 licensing round, Chinese companies secured 10 oil and gas projects. No U.S. major participated. Chinese firms now operate across Wasit, Diwaniyah, Basra, Najaf and beyond.
But China’s rise in the upstream sector does not mean Washington lost its grip. Iraqi oil revenues flow through a Central Bank of Iraq account at the Federal Reserve Bank of New York, giving the United States direct leverage over Baghdad’s access to its own dollars. Executive Order 13303, issued in May 2003 and renewed by successive administrations, protects Iraqi petroleum proceeds from attachment in U.S. courts.
A Reuters investigation in January 2026 described this as effective U.S. control over a critical choke point in Iraqi state finance. The arrangement is not corporate ownership of oil, but it exposes the political economy behind the occupation more clearly than a simple tale of physical plunder.
The federal model kept Iraqi reserves as state property. Foreign companies work under technical service contracts with limited upside – a structure that frustrated western majors, which sought higher margins and predictable terms. 
Chinese state-owned firms approached the same terrain differently, accepting lower margins, longer horizons and higher risk.
They draw on integrated supply chains, lower costs, Chinese equipment and engineering depth. They also buy Iraqi crude, linking field participation to a wider trading relationship.
The United States and Britain used the invasion to assert a new doctrine above international law. But the contracts and political conditions did not produce the high-profit field order western majors preferred. Chinese companies occupied the space they left behind.
Iraq’s post-2003 oil order is therefore not the outcome the war’s architects designed. The U.S. retains financial leverage through New York. China holds the ground in the fields. 
The invasion opened Iraq to foreign capital – but the firms most willing to work its fields are increasingly not from the states that invaded. They are Chinese, and their rise is one of the clearest signs that the postwar order escaped the hands of its creators.
