Senior European Union officials are in South Africa for a summit with President Cyril Ramaphosa to strengthen trade and diplomatic ties in the face of the Trump administration's confrontational foreign policy. The EU will focus on its biggest trading partner in sub-Saharan Africa after announcing retaliatory tariffs against the US. The summit will explore new avenues for economic cooperation and address trade challenges. The EU will also announce a new investment package to finance green energy projects, improve transport infrastructure, and strengthen vaccine production capacity in South Africa.
