Africa's richest man, Aliko Dangote, plans to invest $50bn in the United States and Europe by 2025, in renewable energy and petrochemicals.
Once the refinery is built, Dangote wants to takeover Arsenal, according to a recent interview. His first move, in the event that he succeeds in buying the club, would be to fire Arsene Wenger.
The 60-year-old Nigerian cement tycoon aims to move into these regions for the first time in 2020 after completing nearly $5 billion of agricultural projects and an $11 billion oil refinery in Nigeria.
"We focus on petrochemicals, but may also invest in other companies", said Dangote.
Dangote says Wenger "has done a good job", but believes "someone else should try his luck".

In May, He signed and agreed a 2-year deal with the Club which keeps him in Emirate Stadium till 2019 despite calls by fans for him to step down. According to reports, he rejected a takeover bid from Russian businessman Alisher Usmanov. "Someone will give them an offer that will make them seriously consider walking away. And when we finish the refinery, I think we will be in a position to do that", Dangote said.
"It's a great team, well-run".
Dangote, whose cement unit is Nigeria's biggest listed company, will start investing outside the African continent by 2020.
The economy, which plunged into its first recession last year, is expected to expand by 1.2% this year, according to the World Bank.
