BEIJING, April 12 (Reuters) - Brazilian President Dilma Rousseff did not press complaints about China's yuan currency with her Chinese counterpart Hu Jintao on Tuesday, but came away from a summit with wider market access and investment pledges that may ease trade friction.
Rousseff also brandished a potential investment of $12 billion by Taiwan's Foxconn , the maker of Apple Inc's iPhone and a vast range of other electronic goods.
Brazilian manufacturers have complained that China's yuan is held so low it is damaging their competitiveness, giving Chinese manufacturers an unfair advantage, which along with an appreciating real has helped fuel rising Chinese exports to Brazil.
But despite earlier signalling she would, Rousseff did not discuss the currency dispute with Hu in their formal meeting in Beijing, Brazil's Minister for Industry and Trade, Fernando Pimentel, told reporters.
"No, it was not (discussed)," was Pimentel's brief response to questions about whether the yuan issue came up in the summit.
That will be a victory of sorts for China, which has resisted international pressure to raise sharply the value of the yuan. But Rousseff did manage to clinch a series of business deals on the first full day of her China visit.
Pimentel said that, as well as an order for 35 mid-sized commercial jets manufactured by Embraer announced earlier in the day, Chinese companies signed investment deals for projects in Brazil worth $1 billion.
Rousseff said her government was talking with several electronics manufacturers about investing in Brazil; they included Taiwan's giant Foxconn, which has based much of its production in mainland China.
"You've got an ample range of investments that go from $300-$400mln to $12 billion over 5-6 years in the case of Foxconn," she told reporters of those discussions.
"They're proposing to us a partnership. They came to us and said we want to invest in Brazil," she said of Foxconn, adding that the company may build computer displays in her country.
Brazil's Science and Technology Minister Aloizio Mercadante said Foxconn and Apple could start making Apple's iPad in Brazil by as soon as late November.
Rousseff said earlier in the day that bilateral trade relations with China needed a qualitative boost to be sustainable.
"Brazilian exports to China are still excessively concentrated in iron ore, soybeans, oil and paper pulp. That's good but not sufficient," Rousseff told a business conference.
"It's important to diversify for our trade to remain sustainable. The key to this relationship is reciprocity in the treatment of investments on both sides," Rousseff said.
A joint declaration from the summit also failed to mention the currency, and made little progress in obtaining Chinese support for a permanent seat for Brazil on the United Nations Security Council. In it China said only it backed Brazil's "aspirations for a more prominent role in the United Nations".
LOPSIDED RELATIONSHIP
Rousseff's five-day visit to China, which started on Tuesday, is intended to gain more concessions in what many Brazilians consider a lopsided trade and investment relationship between Latin America's and Asia's largest economies.
Brazil particularly wants to gain more market access and investments from China for value-added products. Last year 83 percent of its exports were raw material, while 98 percent of its imports from China were manufactured products.
One of the top deals Rousseff will have to show for at home is an order from Chinese airlines, including China Southern , for the Embraer jets, each of which is valued at around $40 million, the company's CEO Frederico Curado said at the sidelines of a business seminar in Beijing.
Separately, Embraer's joint venture in China, Harbin Aircraft Ltd, obtained a permit from Chinese authorities to assemble the company's commercial jet, the Legacy 600.
Since she took office on Jan. 1, Rousseff has adopted a more pragmatic, results-driven foreign policy than her predecessor Luiz Inacio Lula da Silva, who often ignored differences with other developing nations to forge a common front against the United States and Europe.
Other deals announced during Rousseff's visit include research and development centres in the states of Goias and Sao Paulo, each worth $300 million.
Brazil's meat packer Marfrig is investing $250 million in six distribution centres in China.
Brazil's oil giant Petrobras signed technology transfer agreements with Sinopec and Sinochem to develop Brazil's vast, new off-shore reserves and increase output at mature oil fields, respectively.
Rousseff is set to meet other Chinese officials on Wednesday before heading to the southern island of Hainan for a summit on Thursday of the BRICS nations that also include Russia, India and new member South Africa.
