Brazil is courting fresh investment from top Chinese grains trader COFCO, as the company plays a growing role in the South American nation's booming farm exports, Reuters reported, citing Agriculture Minister Carlos Favaro on Monday.

Favaro proposed investing in Brazilian railways and waterways to COFCO's board during a meeting in Beijing last week, he said, as well as financing the restoration of farmland.

COFCO has already invested in Santos, Brazil's top soybean port, and is currently expanding its export terminal capacity to 14 million tonnes to help it feed China's voracious demand for soybeans.

But Brazil is also a new supplier of corn to China. COFCO was a key player in opening up the market late last year to Brazilian supplies, said Favaro, and behind the purchase of all 1.5 million tonnes of corn shipped to China so far.

Favaro travelled to Beijing last week. China's customs authority approved four new Brazilian meat plants for export to the country during Favaro's visit.

An agreement to allow for electronic certification of meat export facilities will be signed when Lula travels to Beijing, which will speed up approvals, added Favaro.

The minister plans to visit state-owned ChemChina's Syngenta laboratories on Tuesday to discuss gene editing.
