BEIJING -- Xi Jinping, general secretary of the Communist Party of China (CPC) Central Committee and Chinese president, and Luiz Inacio Lula da Silva, honorary president of the Workers' Party of Brazil (PT) and Brazilian president, have sent congratulatory letters separately to the 7th theory seminar of the CPC and the PT held in Beijing on Tuesday.

In his letter, Xi said that the 20th National Congress of the CPC in October 2022 made it clear that the Party's central task is to lead the Chinese people of all ethnic groups in a concerted effort to realize the Second Centenary Goal of building China into a great modern socialist country in all respects and to advance the rejuvenation of the Chinese nation on all fronts through a Chinese path to modernization.

Xi noted that after the PT returned to power in January 2023, it had vigorously promoted development strategies and stayed committed to achieving sustainable and comprehensive development of Brazil.

He said the seminar focused on strengthening the ruling party building and exploring the path to modernization, which is timely and of great significance to strengthening the capacity building of the ruling parties of the two countries and exploring the modernization paths suited for their own national conditions.

Xi also noted that this year marks the 50th anniversary of the China-Brazil diplomatic ties and the 40th anniversary of the establishment of the CPC-PT relations.

The CPC is willing to deepen exchanges and mutual learning with the PT on governance, and promote party building and national development, so as to make greater contributions to the continuous development of China-Brazil relations in the new era and the building of a community with a shared future for mankind, Xi said.

Lula said in his letter that last year, he and General Secretary Xi had worked together to take the two countries' comprehensive strategic partnership to a new level.

Brazil-China relations are important not only to the two countries but also to the whole world, Lula said, noting that the two sides will work together to consolidate traditional mechanisms of global governance such as the United Nations, while strengthening key mechanisms of South-South cooperation such as the Group of 77 and China, BRICS, the China-CELAC Forum and the BASIC countries.

Lula said that the relationship between the PT and the CPC is an important part of the relationship between the two countries. The visit to China by the delegation of senior Workers' Party officials and their attendance at the seminar aimed to exchange experience on governance and conduct in-depth discussions and cooperation with the CPC on issues of common interest.

He expressed the confidence that the exchanges between the two parties, the two governments and the two peoples will be closer and more fruitful.
