With the harvest underway, representatives of Northwest wheat growers say they're optimistic, though cautious, about prospects for Japan to resume buying their grain.
Sales were suspended after an Eastern Oregon farmer found unapproved genetically modified wheat in a field.
South Korea and Taiwan also halted purchases of western white wheat, but they have resumed buying.
A spokesman for the trade group U.S. Wheat Associates tells the East Oregonian a Japanese agency has tested 1.2 million metric tons of U.S. wheat for GMO material without finding any.
Wheat groups were also cheered when Japan purchased more than 24,000 metric tons of club wheat last week. That's a subclass of western white wheat also grown primarily in Washington and Oregon.
