China has been patrolling the waters around Taiwan with its newest attack submarines carrying supersonic missiles.
The Type-039C Yuans, that was only commissioned in July, have been deployed in China’s East Sea Fleet and is the cutting edge of the country’s non-nuclear submarines.
It comes as Taiwan accused China of exaggeration and "tricks" on Tuesday after the Chinese military published footage of the strategically located Penghu islands where there is a major Taiwanese air base.
