The 19th Heads of State and Government Summit of the Group of 20 (G20) will take place in November 2024 in Rio de Janeiro, marking Brazil's first term as the G20 rotating presidency as South America’s largest economy.

Ana Cristina Carvalho, Chair of the Tourism Association at Federation Chambers of Foreign Trade (FCCE) of Brazil, shared in an interview with China News Network that this year, which marks the 50th anniversary of Brazil-China diplomatic ties, has seen significant progress in bilateral relations. In particular, enhanced diplomatic relations have made travel between the two countries more accessible.

Ana further noted that this year’s G20 in Rio offers a comprehensive platform for participants to discuss topics such as health, education, and urban quality of life. Brazil looks forward to proposing and adopting initiatives at the G20, which will contribute to global development. (Hao Yunhui, Zhao Li)
