Poor soy crushing margins in China that have led the country to default on soy purchases are short term and should improve in two to three months, Bunge Ltd's chief executive officer said. CEO Soren Schroder was in Brazil for the inauguration on Friday of Bunge's terminal in Barcarena in Para state on Brazil's northern coast, which cost 700 million reais ($314 million) to build and has a capacity of 4 million tonnes. "Margins in China are bad for everyone," Schroder said at a dinner late on Thursday. But "it's a short-term problem," he added.
