The presence of Chinese President Xi Jinping at the 19th G20 Summit, which took place in Rio de Janeiro, Brazil from Sunday to Tuesday, was an important part of the summit’s success, according to Marcio Macedo, the Minister of State of the General Secretariat of Presidency of Brazil .
At the summit this year, world leaders including Xi addressed global challenges including infrastructure and technology.
Xi said he was ready to be a partner in the effort to build what he called "a just world of common development," reminding the summit leaders of China's success in lifting 800 million people out of poverty and achieving the United Nation's 2030 poverty reduction target ahead of schedule.
Macedo said in an interview that China’s participation in the G20 was very important to facilitate exchanges between world leaders in multiple fields.
"The presence of the Chinese president in Brazil at the G20 is very important. China has very significant trade relations with Brazil. So, it is important to participate in exchanges like the G20, on important issues such as combating hunger, tackling climate change, fair energy transition, a new global governance and bilateral relations which deal with matters of economic interest for both China and Brazil,” said Macedo.
In the summit's final declaration, participants called for reform of the UN Security Council, and to strengthen the role of multilateral financial institutions like the IMF and the World Bank to ensure greater representation for all countries.
Spanning 22 pages, the declaration also addressed global conflicts, calling for an end to the conflicts in Ukraine and the Middle East, while expressing deep concern regarding the humanitarian crisis in Gaza.
Brazil's government says its year-long run as head of the G20 was a success, especially because of the first-time inclusion of the voices of activists, NGOs, women, and indigenous people in the parallel "social summit."
"The G20 social summit permeated the discussions among all the heads of state, and in my opinion, the outcome couldn't have been more positive, bringing together finance, politics and civil society," said Macedo.
