BRASILIA, Nov. 21 (Xinhua) -- Visiting Chinese President Xi Jinping and Brazilian President Luiz Inacio Lula da Silva on Wednesday announced an elevation of bilateral ties to a "community with a shared future for a more just world and a more sustainable planet."

The announcement, made during Xi's state visit to Brazil, was further bolstered by the leaders' commitment to align the China-proposed Belt and Road Initiative (BRI) with Brazil's development strategies.

MUSICAL PRELUDE TO FRIENDSHIP

The warmth of China-Brazil relations was on full display during a grand welcoming ceremony hosted by Lula on Wednesday.

The ceremony featured a deeply touching moment: a Brazilian singer performed the iconic Chinese song My Motherland in the Chinese language.

It was a reciprocal gesture. When Lula visited China last year, the Chinese side played the Brazilian song Novo Tempo, or A New Time in English, at the welcoming ceremony.

Both songs carry profound significance in their respective nations. My Motherland, an ode to the Chinese people's enduring resilience and love for their country, resonates deeply with the Chinese people, while Novo Tempo, with its hopeful lyrics about a brighter future, symbolizes Brazil's aspirations for progress and renewal even in difficult times.

The choice of the two songs underscores a deep understanding between the two countries: they recognize and honor what each holds most dear.

During his meeting with Lula, Xi said he was deeply touched by the great importance Lula attaches to the China-Brazil relations and his deep friendship toward the Chinese people, as reflected by the grand welcoming ceremony of the highest courtesy accorded to Xi.

Brazil and China are good friends that respect and depend on each other, said Lula at the meeting, adding that China is Brazil's most important strategic partner, and the Chinese people are the most trustworthy friends of the Brazilian people.

Xi's visit to Brazil, his fifth to the South American nation, comes as the two major developing countries celebrate five decades of diplomatic relations.

During the meeting, Xi emphasized the deep ties forged over the past half-century, noting the two sides found a right way for major developing countries to get along with each other, one that is based on mutual respect, mutual benefit, amity and win-win cooperation.

Brazil holds a unique place in China's global partnerships. It is the first country to establish a strategic partnership with China. It is also the first nation in Latin America to enter into a comprehensive strategic partnership with China.

For Julio Bandeira, author of the historical book "Brazil en Route to China," the Brazilian people have a long history of loving Chinese culture and being close to the Chinese people.

"Today, the overseas Chinese in Brazil have also made great contributions to the Brazilian economy and society," he said.

SYNERGIZING DEVELOPMENT STRATEGIES

At the heart of the leaders' discussions was a commitment to align the BRI with Brazil's key development strategies. These strategies aim to modernize Brazil's infrastructure and strengthen regional connectivity, goals that echo the BRI's mission of enhancing global trade and development through shared infrastructure.

The two sides should deepen cooperation in priority areas such as economy and trade, finance, science and technology, infrastructure and environmental protection, and strengthen cooperation in emerging fields such as energy transition, the digital economy, artificial intelligence and green mining, Xi said when jointly meeting the press with Lula after their talks.

Lula, for his part, highlighted plans to focus on expanding and deepening cooperation in areas such as sustainable development, infrastructure, finance, energy transition, and aerospace.

Concrete projects are already underway. For example, the Belo Monte UHV transmission project, which creates an "electricity expressway" linking north and south of Brazil, has not only provided adequate power to industrial hubs there, but also solved the power shortage problem for over 22 million Brazilians.

Meanwhile, Brazil's abundant renewable resources, including hydroelectric, solar, and wind energy, align seamlessly with China's expertise in clean energy technology and manufacturing.

Over the past years, Chinese companies have been actively participating in Brazil's renewable energy sector, particularly in large-scale solar and wind projects, contributing to job creation and technological upgrades in the country.

In a signed article published in Brazilian media ahead of his visit, Xi called on both countries to "seize the opportunities offered by the times" as the new sci-tech revolution and industrial transformation gather pace.

"We should foster more exemplary projects that align with the trend of the times and deliver lasting benefits to the people, and contribute to the common development of our countries and regions," Xi wrote.

Gleisi Hoffmann, president of Brazil's Workers' Party, highlighted the steady growth of economic and trade relations between Brazil and China over the past 50 years. She noted that the partnership has not only met the needs of both nations but also leveraged their respective strengths to create complementary cooperation.

In recent years, she said, China has achieved remarkable progress in areas such as technology, education, and health. Looking ahead, Hoffmann expressed confidence in the potential to deepen collaboration in these fields, envisioning a future marked by what she described as a "new golden 50 years."

China is promoting high-quality development with new quality productive forces, said Mayara Araujo, a researcher from Brazil's Fluminense Federal University, referring to advanced productivity that features high-tech, high efficiency and high quality.

Linking Brazil's development strategies with the BRI will bring more new opportunities to improve and upgrade cooperation between the two countries, said Araujo.

STRENGTHENED VOICE FOR GLOBAL SOUTH

The elevation of China-Brazil ties to a community with a shared future for a more just world and a more sustainable planet came shortly after the 19th G20 Summit held in Rio de Janeiro, Brazil.

With the theme "Building a just world and a sustainable planet," this G20 summit offered a vital platform for leaders to address urgent global challenges, including hunger, economic inequity, and climate change.

After calling on Monday for a just world of common development and a fair and equitable global governance system, Xi on Wednesday called on both countries to step forward for world peace and justice.

The two sides should practice true multilateralism, speak up and act for justice, and make global governance more just and equitable, Xi said during his meeting with Lula.

As major developing countries, China and Brazil should take the lead in championing discussion and consultation, promoting global solidarity, and jointly tackling global challenges that affect the future of humanity, Xi added.

Brazil and China are both committed to expanding the participation of developing countries in the decision-making processes of international organizations, said Evandro Menezes de Carvalho, professor at Brazil's Getulio Vargas Foundation.

Moreover, their collaboration within mechanisms such as BRICS demonstrates how they can unite around shared goals and translate that solidarity into concrete actions with substantial impact, said the expert, noting that it is precisely for this reason that an increasing number of developing countries are eager to join these institutions.
