Last month, Masisi threatened to walk away from talks to renew the sales deal with DeBeers unless Botswana gets a larger share of output from the joint venture. He did not specify the size of the share it sought.
Botswana and De Beers mine diamonds under an equally-owned joint venture, Debswana.
Three-quarters of Debswana's production, which was 24 million carats in 2022, is sold to De Beers. The balance is sold to state-owned Okavango Diamond Company(ODC), which was set up under the current 2011 sales deal as Botswana sought to market gems outside the De Beers system.
Masisi told reporters on Thursday that Botswana had denied itself the opportunity to sell its own diamonds through the 54 year-old joint venture agreement.
He added that the experience of selling diamonds outside the De Beers system, which sells unpolished, or rough, stones, had shown that Botswana could get more revenue.
“Besides the fact that the diamonds are ours, it doesn’t make sense for us to continue to relegate ourselves to participating in the rough space only. So, it’s only logical that we want more and we are going to get more. But through negotiation," Masisi said.
De Beers Chief Executive Officer Al Cook, who met Masisi in Gaborone on Friday morning, said he had a "constructive discussion" with the president.
"It's very clear that, front and foremost in the president's mind is the interest of the Botswana people. We as De Beers want to play our role in a strong, strategic partnership. I'm very confident that this partnership will go forward in a very good way," Cook told reporters after the meeting.
De Beers says Botswana's government receives more than 80% of returns from Debswana, including taxes and royalties.
