DP World is asking the US to help it collect nearly $500m in final arbitration awards from Djibouti.

And the United Arab Emirates ports and logistics giant's Doraleh Container Terminal joint venture still has more outstanding, and possibly even larger, claims against the East African city-state.

The claims are part of the dispute over Djibouti's 2018 ouster of DP World in favour of China Merchants Port Holdings, a spin-off of China Merchants Group.
