BRASILIA, April 25 (Xinhua) -- Agriculture and biotechnology are key to China-Brazil cooperation and have ample room for future growth, experts said here Thursday.

Government and private-sector representatives attending the opening of a seminar titled "Agriculture and Biotechnology -- Brazil and China" agreed the subject is central to the future of bilateral ties.

China is the leading market for Brazil's agricultural goods, accounting for up to 38 percent of the sector's total sales, according to the National Agriculture Confederation (CNA) in Brasilia, which hosted the event.

CNA President Joao Martins expressed the sector's commitment to contributing to China's food security.

"The Chinese market is enormous. With a population that demands high quality products and a permanent increase in profits, China aims to stay at the top of our priorities in foreign policy and trade policy," said Martins, adding that "we need to expand our exports to China with new products."

Biotechnology is essential for guaranteeing high quality and boosting Brazil's agricultural productivity, he said.

Chinese Ambassador to Brazil Yang Wanming noted agricultural trade has seen rapid growth over the past 10 years, with major Chinese agribusinesses developing projects in Brazil, especially in fields ranging from infrastructure to efficient export of goods.

"From now on, given the changing consumer habits of the Chinese, the demand for quality agricultural products will increase, and the potential of a market of nearly 1.4 billion will be even greater. That will generate unlimited opportunities for Brazil, the global granary of the 21st century," said Yang.
