JOHANNESBURG (AP) — World leaders arrived Friday for a historic first Group of 20 summit in Africa that aims to put the problems of poor countries at the top of the global agenda but has been undermined by a rift between host South Africa and the United States over a Trump administration boycott.

The weekend summit in Johannesburg will be attended by delegations from 18 of the world’s richest and top developing economies — minus the U.S., which has branded South Africa’s hosting a “disgrace ” and won’t participate in the talks.

The boycott by the world’s biggest economy and founding G20 member was ordered by U.S. President Donald Trump over his claims that majority-Black South Africa is persecuting its white Afrikaner minority.
