Russian President Vladimir Putin will not travel to next week's BRICS summit in Brazil because of an outstanding arrest warrant issued against him by the International Criminal Court (ICC), Kremlin foreign policy aide Yuri Ushakov said on Wednesday.

President Xi Jinping will miss a meeting of BRICS leaders in Rio de Janeiro, according to a Brazilian official familiar with the matter, marking the first time the Chinese leader has skipped the summit since taking power.

Chinese foreign ministry spokesman Guo Jiakun told Brazilian newspaper Folha de S.Paulo that information about Xi's participation in the summit will be shared at the "appropriate time". Guo added that China supported Brazil’s BRICS presidency and sought to “promote deeper cooperation” among its members.
