Brazilian President Luiz Inácio Lula da Silva was in the Chinese financial hub of Shanghai on Thursday as he looks to boost ties with the South American giant's biggest trade partner and win political support for attempts to mediate the conflict in Ukraine. Lula arrived late on Wednesday and is due to meet with his Chinese counterpart Xi Jinping in Beijing on Friday before concluding his visit on Saturday. The Brazilian government says the sides are expected to sign at least 20 bilateral agreements during Lula's trip, underscoring the improvement in relations following a rocky patch under predecessor Jair Bolsonaro. In Shanghai, Lula will also attend the official swearing in of close adviser and former Brazilian president Dilma Rousseff as head of the Chinese-backed New Development Bank.
