Kenya’s president says he has cancelled multimillion-dollar airport expansion and energy deals with Indian tycoon Gautam Adani after U.S. bribery and fraud indictments against one of Asia’s richest men.

It follows accusations that Adani was scheming to pay over $250 million in bribes to Indian government officials, which he denies.

Kenya has terminated two high-profile agreements with India’s Adani Group, intensifying scrutiny on the conglomerate, which is already reeling from allegations of bribery by US authorities.
