An economic downturn has the Brazilian government turning to anti-dumping measures against China and other countries, according to analysts.

Last month the Brazilian Foreign Trade Chamber made antidumping charges levied on float glass imports from China and five other countries permanent. The duties were also placed on imports from the United States, Saudi Arabia, Egypt, the United Arab Emirates and Mexico. Brazil's Secex foreign trade bureau also imposed antidumping penalties on boron-added steel plate from China and Ukraine in December.

Last fall, BrazilianPresident Dilma Rousseff narrowly won re-election amid a struggling economy.The country has been battling high inflation and a sharp decline in private investment. The downturn in commodity prices has hit Brazil hard. A good example is iron ore where the price fell 40 percent in 2014 due to new capacity from Australian mining companies and a slowdown in China reducing demand.

All of this has increased the government's interest in antidumping measures, according to Christopher Cloutier, a partner in the King & Spalding law firm's international trade practice in Washington and a former member of the US embassy staff in China.

He has taken part frequently on behalf of the US in Chinese government trade proceedings and in negotiations with the Chinese government.

"One legal requirement for the imposition of antidumping duties is that the competing domestic industry must be suffering injury, and it's much easier to show injury during an economic downturn," he told China Daily in an e-mail.

China became Brazil's biggest trading partner in 2009 when it overtook the US. "The trading relationship between the two countries is complicated and unbalanced in terms of the nature of the goods being traded. While Brazil primarily exports commodities to China, such as iron ore, soybeans and oil, China is increasingly exporting high value-added manufactured and high-tech goods to Brazil. This imbalance has skyrocketed over the last 13 years," said Nathalie Hoffman, founder and CEO of Brazil Business Link in Marina del Rey, California.

His firm provides consulting and business development services to companies seeking to enter or expand operations in Brazil.

Hoffman noted that a change in the character of the Chinese imports is raising concerns in Brazil.

"China competes head-to-head with Brazil in certain Latin American export markets, with China taking market share away from the Brazilians. Furthermore, Brazil used to run a trade surplus with China. But now that iron ore prices have lost about 40 percent of their value, Brazil is now running a trading deficit," she said.

Cloutier said trade is increasing, but from the perspective of many in Brazil, it's not balanced trade. "Brazil provides raw materials to China that are then processed in Chinese factories, incorporated into higher value-added products, and then shipped from China to export markets including Brazil," Cloutier explained.

"In 1996, about 26 percent of Brazilian exports to China were of primary commodities, but now more than half of Brazilian exports to China are of primary products. Conversely, in 1996 about one quarter of Chinese exports to Brazil was of high-technology products but now that value is above one half."

Cloutier said the trend is clearly for an increasing number of Brazilian antidumping investigations targeting China.

"In 2013, Brazil initiated a total of 38 antidumping investigations, 10 of which - about one quarter - targeted China. In 2014, Brazil reported to the World Trade Organization that it initiated 66 antidumping investigations. China was targeted in 16 of these new investigations, still about a quarter of all cases," he said.

Although China accounts for the highest proportion of cases, it's hardly the only target. In 2014, for example, imports from the United States were targeted in six antidumping investigations initiated by Brazil and in 2013 South Korea was the target in five cases, he said.
