How are escalating US-China trade tensions and Trump's foreign aid policies affecting global economic relations and vulnerable populations?

The escalating US-China trade war involves tit-for-tat tariffs, with Trump imposing 10% additional tariffs on hundreds of billions in Chinese imports, while China retaliated with duties on nearly $14 billion worth of US goods. Despite these measures, tensions appear controlled with room for negotiation between the world's two largest economies. Meanwhile, Trump's decision to halt US aid to South Africa over controversial land laws and the country's stance on Gaza raises concerns about weaponizing humanitarian assistance. This broader foreign policy shift, including potential shutdown of the main US foreign aid agency, could significantly impact millions of vulnerable people worldwide who depend on American humanitarian support.
