South Africa no gree make dem vex am when US President Donald Trump talk for event for Miami on November 5 say him and no American official no go attend the G20 leaders summit wey dem dey plan for Johannesburg later this month.

Tone and way wey Trump announce am—him call am a "total disgrace" say South Africa dey host the event, and him talk claims wey people don widely discredit about how dem dey kill white people for that country—e get one familiar ring to am.

Small days before, him don point finger at Nigeria with allegation of a "Christian genocide" and him mark am as a "Country of Particular Concern"—move wey many dey see as try to calm evangelical groups and some lawmakers for the US.

Dis latest talk wey Trump dey do against one African country dey try distract from the historical meaning of the summit on November 22–23, since na the first time dem go hold G20 for the continent.

Experts say say Trump boycott for the Johannesburg G20 no too concern South Africa domestic policy; instead e show the growing attack on multilateral bodies wey dey give Africa chance to engage with the worlds richest nations.

Other countries don use the US position as chance to harden their own stance, especially the European Union.

"Na early signs dem be. I think more negative developments go show when members of these bodies begin no participate for selfish reasons," Prof David Monyae from the University of Johannesburg tell TRT Afrika.

"E dey speak to one imperialistic idea where people think say Africa suppose just be appendage of the Western world, something wey the Global South dey fight against through calls to change multilateral institutions like the World Bank and the UN Security Council."

How e fit affect diplomacy

Experts warn say US absence for the G20 summit fit cause gbege and damage the outcome and legacy of the Johannesburg meeting, because e go make it hard to get binding consensus—even if na only perception—on the issues wey dem dey discuss.

The boycott by the richest G20 member come from tension between Pretoria and Washington after one "tense Oval Office meeting" in May, where Trump raise claims about the killing of Afrikaners (descendants of the first colonial settlers) and say dem dey confiscate their land.

South African President Cyril Ramaphosa, with support from some Afrikaners, strongly deny those claims. Even so, the US offer refugee status to some Afrikaners wey wan relocate there. Trump later carry the matter further for his campaign, saying South Africa suppose comot from the G20.

Pretoria at first dey hesitate to respond formally to the US boycott. E wait until last Wednesday before President Ramaphosa reply, saying that "boycotting never really works."

"The United States, by not being at the G20, must never think that we are not going to go on with the G20. The G20 will go on. All other heads of state will be here. In the end, we will take fundamental decisions, and their absence is their loss," Ramaphosa tell journalists.

Critical policy platform

G20 na group of leading economies wey include 19 countries plus two regional bodies—the European Union and the African Union. South Africa be the only member state from Africa.

G20 members represent about 85% of the worlds GDP and roughly two-thirds of the global population. The presidency of the group dey rotate every year, and the US suppose take over from South Africa after this summit.

Pretoria wan use the summit to push Global South priorities under the theme "Solidarity, Equality, Sustainability", a theme wey the Trump administration don call anti-American.

Observers fear say the US fit reject or back out from decisions wey dem go make for Johannesburg and choose to start afresh at the next summit.

Already, talks wey finance ministers and central bankers hold for February about global economic matters end without consensus because some key people no show, including the US finance chief. A meeting of health ministers last week also finish without a draft declaration on global access to health after US officials waka comot.

"E pain say participation don turn weapon for powerful countries to weaken a once-bold ministerial declaration wey follow the themes wey South African government put front," Javid Abdelmoneim, president of the medical charity Doctors Without Borders (Médecins Sans Frontières), tell journalists after the health ministers meeting.

Isolating South Africa

South Africa effort to fix the relationship with the US no too work. Trump problem dey partly over South Africa position on Palestine, as Ramaphosas government don take Israel go the International Court of Justice over allegations of genocide.

Pretoria join BRICS also dey cause wahala, because that grouping dey appear like counterweight to the US-led world order.

Ramaphosa government dey negotiate for better tariff deal with the US after the Trump administration put a 30% import tax on South Africa in August—the highest rate for sub-Saharan Africa.

The South African president talk earlier this month say him dey look forward to conclude an agreement "fairly soon."

Experts believe say South Africa need join other emerging markets inside BRICS and like-minded countries to reduce the damage if stalemate continue.

"Realignment of these relations go be the main work for South Africa," Prof Monyae explain. "These Trump lies no go last. I think world dey already sabi. No doubt e go cause some damage since him be leader of the most powerful country, but e no go stand for long term."

If South Africa hand over the G20 presidency back to the US after the summit, e for mark the return of the baton to the Global North after presidencies of Brazil, India and Indonesia. But Trump boycott of the landmark Johannesburg summit don already make sure say no ceremonial handover go happen.
