By Brenda Goh BEIJING (Reuters) -Chinese President Xi Jinping used a visit to Shanghai on Tuesday to push for breakthroughs in artificial intelligence and underscore China’s leading role in the "Global South".

China is reportedly conducting a global diplomatic campaign to oppose President Donald Trump’s new trade deals with US allies. According to a Bloomberg report on Tuesday, Beijing is trying to reframe itself as a global rules-based order defender and make other countries see Washington as an unreliable trading partner.

Chinese Foreign Minister Wang Yi called for resistance against what he described as a "bully," referring to U.S. President Donald Trump. The diplomat warned against giving in to the Republican's demands on tariffs.
