LONDON: Angola has cut the number of oil cargoes that it will ship to Chinese state firms to pay down debt to Beijing as it seeks to renegotiate repayment terms to deal with the crippling impact of the coronavirus, three sources familiar with the matter said.

Angola said this week it had asked for G20 debt relief and was in advanced talks with some countries importing its oil on adjusting financing facilities, but expects no further debt overhaul to be needed beyond this. The sharp global economic slowdown due to the novel coronavirus pandemic pushed Brent oil prices to their lowest levels since the late 1990s and U.S. oil futures to negative territory for the first time in history.

The price drop has put heavily-indebted Angola into a fragile state as it derives a third of state revenues from oil. By far, its biggest creditor is China. Analysts say Angola has over $20 billion in bilateral debt with the lion's share owed to China. Much of the cash was borrowed to build roads, hospitals, houses and railways across the southern African country.
