Brazil's President Luiz Inacio Lula da Silva says that emerging BRICS economies did not want to live under an "emperor", after Donald Trump declared a 10% tariffs hike on members for their allegedly anti-American policies. "I don't think it's very responsible or serious for the president of a country as big as the United States to go around threatening the world through the internet. It's not right. The world has changed. We don't want an emperor," he tells journalists at a press conference following a two day BRICS summit in Rio de Janeiro. SOUNDBITE
