Secretary of Agriculture Dan Glickman says any reforms of U.S. export subsidy programs depend on what other nations are willing to do with their own agricultural export subsidy schemes.  The United States won't act unilaterally to change its export subsidies, he adds.

USDA provides credit guarantees through the GSM program to make it easier for importing countries to buy U.S. farm products.  Other countries claim this gives U.S. farmers an unfair trade advantage.

"We won't talk about reforming our export credit program until export subsidies are on the table as well," Glickman told the National Association of Agricultural Journalists.
