Brazilian President Jair Bolsonaro and Chinese President Xi Jinping praised their countries' strong bilateral relations at a meeting on Wednesday, as sources said a Chinese state firm was prepared to announce a major Brazil port investment.

The leaders' comments showed how far relations have come since Bolsonaro's repeated bashing of China on the campaign trail last year, which sparked concerns that he could disrupt one of the world's biggest trading partnerships.

Still, there were few major announcements at the start of Xi's visit to Brasilia, only a few weeks after Bolsonaro's official visit to Beijing.
