The 10-day naval exercises are a show of diplomatic independence for South Africa, which is part of an alliance with Brazil, Russia, India and China — known as BRICS.

JOHANNESBURG — South African  s military announced on Thursday that it plans to hold joint training exercises off its coast next month with Russia and China, a move criticized by the United States, which has been trying to rally other countries to isolate Russia over the war in Ukraine.

The exercises will coincide with the one-year anniversary of the start of Russia’s invasion of Ukraine on Feb 24. South Africa was among three dozen countries that abstained last year in a vote in the United Nations to condemn Russia for its claim to have annexed several regions of Ukraine.

South Africa has conducted military exercises with Russia and China before, as well as with the United States and NATO countries. The South African National Defense Force said that the upcoming drills, to be held from Feb. 17 to 27 near the coastal towns of Durban and Richards Bay, are a “means to strengthen the already flourishing relations between South Africa, Russia and China.”

The United States, which has fostered a decades-long strategic partnership with South Africa, immediately expressed disapproval. David Feldmann, a spokesman for the United States Embassy in Pretoria, South Africa, said in a statement, “We note with concern” the plan by South Africa to move ahead with the joint exercises “even as Moscow continues its brutal and unlawful invasion of Ukraine.”

The naval drill is a show of diplomatic independence for South Africa, analysts said. South Africa is part of an alliance with Brazil, Russia, India and China — known by the acronym BRICS — and this naval exercise reasserts South Africa’s position that it will not allow the conflict between Russia and Ukraine to dictate its diplomatic relations.

“It is seen as a war that is happening in Europe, and as far as South Africa is concerned, it’s not part of this war,” said Denys Reva, a maritime researcher with the Institute for Security Studies in South Africa.

Although the European Union is South Africa’s largest trading partner, South Africa’s governing party, the African National Congress, has held deep historical ties to Russia and China because of the help those countries provided in the fight against apartheid.
