The G20 summit in Rio de Janeiro this week will address critical issues such as climate change, the crisis in the Middle East, the war in Ukraine, and global poverty. However, with the impending arrival of President-elect Donald Trump to the White House, there are concerns about what can be achieved in President Joe Biden's final act. The narrative around support for Ukraine is already shifting, as Trump has indicated his intention to end the war and allies are already blinking. The world will be watching to see how allies 'Trump proof' their actions in Rio, including economic ties with China and support for Ukraine. Additionally, the summit is facing challenges on issues such as taxation of the super-rich and climate finance. Meanwhile, the UK is pursuing economic partnerships with countries like China, Brazil, and Indonesia, as well as tackling the small boats crisis through deals with countries like Tunisia, Libya, Kurdistan, Turkey, and Vietnam.
