Brazilian President Luiz Inácio Lula da Silva heralds his desire to establish an "indestructible" relationship with China, as leaders of the three largest economies of Latin America flew to Beijing against the backdrop of Donald Trump's trade war, and deep international uncertainty about his presidency has emerged.

Lula made a four-day state visit in the Chinese capital on Sunday, accompanied by a delegation of 11 ministers, top politicians and more than 150 business leaders.

A few hours later, Colombia's President Gustavo Petro arrived, taking a line for the Great Wall of China and declaring that he longed for South American countries to "look only one way" for the United States. "We decided to take a big step between China and Latin America," Petro said.

Chile's Gabriel Boric also traveled to Beijing to attend a meeting between representatives from Latin American and Caribbean countries (CELAC) and China on Tuesday.

Lula spoke to hundreds of Chinese and Brazilian business leaders in the Chinese capital on Monday, hitting a crackdown on Trump's tariffs, saying he could not accept "the measures the U.S. president tried to impose on the planet from one day to the next."

The Brazilian leftist said he hopes to establish "essential" relationships with China - which is already Brazil's top trading partner - and praised his Communist host for his officials' announcement of $4.6 billion (£3.5 billion) in China. Lula is scheduled to meet with Chinese leader Xi Jinping, who is expected to return to the visit in July, when Xi Jinping travelled to the BRICS summit in Rio de Janeiro.

"China is often seen as an enemy of global trade when it actually acts like an example of a country trying to do business with countries over the past 30 years," Lula said.

Over the past 25 years, the visits of the three South American leaders to China have highlighted the fast-growing footprint of East Asian countries, in which it has become a greedy consumer of commodities such as soybeans, iron ore and copper. Chinese companies also poured into the region. It can be seen that electric cars made by Chinese manufacturer Byd can be seen parading the streets of Brazilian cities, from Brasília to Boa Vista deep in the Amazon.

The visit also globally for Trump’s turbulent president, anxiety in Latin America and concerns about the U.S. president’s plan to a region he threatens to “take back” the Panama Canal and those who are suspicious.

Matias Spektor, professor of international relations at the Brazilian IQ and Vargas Foundation, said the existence of three South American presidents in Beijing emphasized that in the Trump era, these leaders increasingly contacted the rest of the world as the United States retreated.

“It tells us that all the world is willing to go out…to take advantage of all the opportunities in the international system – and there are a lot. Because with the U.S. turning to free trade, as the U.S. adopts… not deals, predatory policies – countries have the motivation to interact with those who trade.”

“(Lulla) is very active in trying to open trade for Brazil when the United States revokes previous rules of the game, and the new rules of the game are not yet born… These (Latin American) countries want to shape the norms that may appear now.

Latin American leaders such as Lula have long believed that the world is multipolar, Spector said. “What happened on January 20 (with Trump’s return to power), the policy change in Washington, D.C. has spurred the belief that already exists that the global axis of power has been moving eastward for some time and towards the south.”
