In 2018, when President Jair Bolsonaro was just a conservative candidate, he was known for being outspoken against China which he always said is set to take advantage of Brazil.

China then didn't respond to Mr. Bolsonaro's remarks during his campaign nor in the early weeks of his presidency.

What China did was it hosted Mr. Bolsonaro at a state visit and signed agreements with Brazil.

Not a year yet into his presidency and with a non-performing economy, Mr. Bolsonaro hosted Chinese President Xi Jinping in Brazil's capital for a two-day summit of the leading emerging nations, the so-called BRICs nations made up of Brazil, Russia, India, China, and South Africa.

Now, Mr. Bolsonaro is expressing interest in getting Chinese capital to finance infrastructure, like railways, roads, ports and power plants, things his government considers necessary for its economy to grow 1% this year. 

Mr. Bolsonaro said that he is "happy with the opportunity to discuss a large bilateral agenda."

He further added that he sees the "Brazil-China cooperation with enthusiasm."

Brazil's president's change of mind comes after disappointments with the US.

Earlier this 2019, Mr. Bolsonaro was sure of America strongly backing up Brazil's request to join the Organization for Economic Cooperation and Development (OECD), the popularly called rich countries' club.

However, Argentina received US support first.

Just two months before, during the Amazon fire crisis, when Brazil's president was getting criticized over his handling of the Amazon, Beijing sided with Brazil.

Even the ambassador, Qu Yuhui, referred to the Amazon crisis as a "bit fabricated."

During his visit to China, Mr. Bolsonaro said that "this support is priceless."

The trade deal of Brazil with the US is only in the early stages and would face issues from American farmers because of Brazil's powerful agricultural sector.

Now, with China as Brazil's largest export market, Mr. Bolsonaro wants to boost sales in the mainland.

Commerce between the two countries reaches $100 billion yearly. 

Not only does China wants his country's commodities but Beijing is interested in expanding its investment portfolio in Brazil.

Marcos Troyjo, Brazil's trade chief, confirmed that they "are discussing ways to expand Brazil exports to China beyond basic materials." 

He added that Brazil wants to include some manufactured goods, mineral products with added value and processed food.

He likewise pointed out that Mr. Bolsonaro has told them "to negotiate with every country" without any bias.

One of the ultimate proofs of the Brazil-China ties is when Brazil upgrades to a fifth-generation cellular network a year from now with China's Huawei Technologies Co. being the most likely technology supplier.

Mr. Trump had been asking U.S. allies to ban Huawei 5G equipment due to alleged cybersecurity risks.
