A senior official overseeing drought relief efforts said China’s wheat crop could suffer significant damage if a long-lasting drought continues, AFP reported. E Jingping said if there was no rain in 15 days, the situation in the wheat zone would become "severe." "This is the critical period of growth for winter crops," he said. Some areas have not seen rain for more than 100 days, and the drought currently affects 96% of China’s winter wheat-growing region. In an attempt to relieve the drought, China has been seeding clouds with chemicals to encourage rainfall.
