Chinese President Xi Jinping invited India on Tuesday to attend a summit of the APEC trade group in November, sending a message of cooperation during the first meeting between the new leaders of the world's most populous countries, Reuters reported. But behind the smiles at Xi's 80-minute meeting with Prime Minister Narendra Modi in Brazil, India's rivalry with its powerful neighbour bubbled up as the two nations argued over who would host the headquarters of a proposed BRICS joint development bank. Xi and Modi met soon after their arrival at a summit of the BRICS group of emerging powers. Xi said the two countries should join hands in setting global rules and suggested he attend the November meeting of the 21-nation APEC in Beijing, as well as take part in Chinese-led regional initiatives.
