A Taiwanese fighter pilot has received disciplinary punishment for dating a Chinese reporter stationed in Taiwan, the defence ministry said on Wednesday.
Although the pilot was not found to have committed any "improper conduct", he had violated regulations, it said, while declining to specify what sort of punishment he would receive.
"The ministry continues to strengthen its anti-spying mechanism to prevent the Chinese communists from prying on our military intelligence," it said in a statement.
The ministry only identified the woman by her surname Li and according to Taiwanese media, she worked for China National Radio.
Taiwan has been rocked by a string of spying scandals in recent years, showing intelligence gathering has continued despite warming ties.
The island's top court last month rejected an appeal by an ex-general sentenced to life in prison for spying for China, the toughest punishment meted out in an espionage case in decades.
Taiwan and China have spied on each other ever since they split in 1949 at the end of a civil war. But Beijing still considers the island part of China and has threatened to use all means necessary to bring about reunification.
