VOInews, Rio De Janeiro : The escalating war in Ukraine and stalled UN climate negotiations dominated the final day of a G20 summit in Brazil on Tuesday (Nov 19), held in the shadow of Donald Trump's looming US presidency.

Chinese President Xi Jinping - the most powerful leader at the summit - repeated his warning of turbulent times ahead, warning his French counterpart Emmanuel Macron in a meeting of increasing "risks and challenges".

Macron told Russia ally Xi that the two shared "converging views" on seeing peace brought about in Ukraine, while also expressing concern about "bellicose and escalatory comments from Russia about its nuclear doctrine".

Xi has sought in vain, with Brazil, to get Russia and Ukraine to the negotiating table but developments in the war are rapidly overtaking diplomacy.

President Joe Biden, at the G20 summit as a diminished figure given Trump's imminent arrival on the world scene, made a last-gasp major policy shift by allowing Ukraine to fire US-supplied long-range missiles into Russia.

Russia, which has warned it will respond if targeted by the weapons, said Tuesday Ukraine fired US ATACMS missiles into its border region.

Macron has called Biden's decision to free Ukraine's hand with US missiles "good". But German Chancellor Olaf Scholz said it would not follow suit and continued to hold out on giving sophisticated Taurus missiles to Kyiv.

The summit statement also had the leaders urging an end to conflict in the Middle East, where Israel is waging offensives in both Gaza and Lebanon. Israel and archenemy Iran have also exchanged fire.
