force of 2,000 Somalis for anti-piracy operations in the Gulf of Aden. The program was funded by several Arab countries, including the United Arab Emirates and backed by the United States. Prince's spokesman, Mark Corallo, said Prince had "no financial role" in the project and declined to answer any questions about Prince's involvement. John Burnett of Maritime Underwater Security Consultants said, "There are 34 nations with naval assets trying to stop piracy and it can only be stopped on land. With Prince's background and rather illustrious reputation, I think it's quite possible that it might work." Private equity investor in Africa Prince leads a private equity firm called Frontier Resource Group, and until April 13, 2021, he was also chairman of Frontier Services Group Ltd, a Bermuda-incorporated logistics and transport company listed on the Hong Kong Stock Exchange. Frontier Services Group is backed by China's state-owned CITIC Group and Hong Kong-based investor , with the Chinese government listed as the largest investor. Prince's ventures advise and support Chinese investment in oil and gas in Africa. In May 2014, it was reported that Prince's plan to build a diesel refinery in South Sudan, in which $10 million had already been invested, was suspended. The halted refinery project was reported to be supported personally by the country's president, Salva Kiir Mayardit. Frontier Services Group was reported to be paid $23.3 million by South Sudan's Ministry of Petroleum to transport supplies and perform maintenance on oil production facilities. Prince sold to the government of South Sudan for $43 million dollars three Mi-24 attack helicopters and two L-39 jets together with the services of Hungarian mercenary pilots to operate the aircraft. One of the Hungarian pilots attracted some infamy by using his Facebook page to boast about his daily killings.

In October 2014, the Kenya Civil Aviation Authority denied Kijipwa Aviation an aviation license renewal. Prince also purchased a 25% stake in Austrian aviation company Airborne Technologies. In 2014, Prince commissioned the company to modify Thrush 510G crop-dusters with surveillance equipment, machine guns, armor, and other weapons, including custom pylons that could mount either NATO or Russian ballistics. One of the modified crop-dusters was delivered to Salva Kiir Mayardit's forces in
