Kuwait signed a $16 billion deal partnering with three North American investors to invest in its domestic and export pipeline network, making it the largest single direct foreign investment in Kuwait’s history.

The Gulf nation’s state-owned Kuwait Petroleum Corporation signed the lease-and-leaseback agreement with Canada’s Brookfield Asset Management and the U.S.’s Blackstone and KKR. The three companies and the KPC subsidiary, Kuwait Oil Company, will form a joint venture in Kuwait that will lease usage rights for 13 KOC crude oil pipelines spanning nearly 200 miles.
