BEIJING (AP) — China says it has sentenced a man to 10 years in prison for leaking classified documents to a foreign spy.

The official China Daily newspaper said on its website Monday that the man stole secret military documents and transferred photographs and other useful information to the foreign party. It didn’t specify its sources.

It identified the man by the surname Li. It named the recipient of the documents as “Feige,” but gave no other information about the person. It said Li also gathered information about military bases in the southern province of Guangdong, home to China’s southern fleet that oversees operations in the sensitive South China Sea.

Interest in the aims of China’s booming military spending has grown in recent years, particularly in the U.S., the region’s primary military power.
