Ukraine and Russia

* The missile that killed two people in Poland was probably not fired from Russia, US President Joe Biden said after an emergency meeting of NATO leaders called to discuss what Poland called a strike by a Russia-made projectile.

* US Treasury Secretary Janet Yellen called for international support for Ukraine and said she wanted to acknowledge a wave of Russian missile attacks on the country in the past day.

* On Tuesday, Ukrainian President Volodymyr Zelenskiy called on earlier on G20 leaders to adopt a 10-point peace formula.

* Russian Foreign Minister Sergei Lavrov, who headed the Russian delegation to the summit in the absence of President Vladimir Putin, condemned "politicisation" of the meeting.

* French President Emmanuel Macron and Chinese President Xi Jinping agreed it was urgent to de-escalate the conflict in Ukraine and reaffirmed their position on preventing the use of nuclear arms there, the French Presidency said.

* United Nations Secretary-General Antonio Guterres had a "very frank and open discussion" on the Black Sea grain deal with Lavrov.

Monetary Policy

* The leaders said their central banks would continue to calibrate the pace of monetary policy tightening, while being mindful of the need to limit "cross-country spillovers".

Climate Change

* G20 leaders agreed to pursue efforts to limit the global temperature increase to 1.5C - confirming the stand by the temperature goal from the 2015 Paris Agreement on climate change. That could boost negotiations at the UN COP27 climate summit in Egypt, where some negotiators feared the G20 would fail to back the 1.5C goal - potentially thwarting a deal on it among the nearly 200 countries at the UN talks.

* Their declaration also said G20 countries would accelerate efforts towards the phasedown of unabated coal power. Negotiators at the COP27 summit in Egypt are wrangling over whether to expand this to phase down all fossil fuels.

* Biden and Chinese leader Xi Jinping agreed on Monday to resume cooperation on climate change.

* A coalition of countries including the United States and Japan announced on Tuesday they would mobilise $20 billion in public and private finance to help Indonesia shut coal power plants and bring forward the sector's peak emissions date by seven years to 2030.

Bilateral Meetings

* Biden said Britain was America's closest ally and closest friend, during his first meeting with Rishi Sunak since he became British prime minister.

* US Treasury Secretary Janet Yellen met for two hours with China's central bank governor, Yi Gang, a US treasury official said, adding that their talks had a "frank, constructive, and positive tone".

* Canadian Prime Minister Justin Trudeau raised "serious concerns" over suspected domestic interference by China in his first talks with President Xi on Tuesday in more than three years, a Canadian government source said.

* India's Prime Minister Narendra Modi discussed global and regional developments in a meeting with Biden and also exchanged courtesies with China's Xi at the end of a dinner in the first such meeting since deadly border clashes in mid-2020.

* South Korean President Yoon Suk-yeol called for China to play a bigger role in reining in North Korea's nuclear and missile provocations, his office said, after talks with Xi. 

* Australian Prime Minister Anthony Albanese and Xi signalled they would seek to move past years of disagreements after the first formal meeting between leaders of their countries since 2016. The meeting was a step to normalising ties but would not bring an Australian defence policy shift, diplomats said.
