China has announced large-scale military exercises in broad swaths of the waters and airspace in both the South and East China seas near Taiwan, days after Beijing said in a defense white paper that it will not renounce the use of force in efforts to reunify Taipei with the mainland.

In two notices posted to the website of China's Maritime Safety Administration late Sunday and early Monday, the body said that entering a large chunk of the airspace and waters off the coast of Zhejiang and Guangdong provinces was prohibited.

The warning said exercises off Zhejiang were scheduled to run through Thursday, while the one for Guangdong would conclude Friday.
