BEIJING, June 12 -- China expects a good harvest of summer crops as a slew of agricultural measures have overcome unfavorable weather conditions, the Ministry of Agriculture said Monday.

Over 70 percent of China's summer grain has been harvested, according to the ministry.

The ministry said the good harvest was due to proper adjustment of the grain-growing pattern, improved production quality and application of green and high-yield technology.

In addition, the government has kept stable wheat purchasing prices to protect farmers' income and interests. Disaster prevention measures have also been put in place to ensure a good harvest, according to the ministry.
