China said it was simulating "sealing off" Taiwan in a third day of drills as it appeared to use an aircraft carrier to launch jets towards the island.
Taiwan said it had detected jets to its east while China said its Shandong aircraft carrier had taken part.
Beijing began the exercises on Saturday after Taiwan President Tsai Ing-wen met the US House Speaker in California.
So far however the drills are not as big as those that followed Nancy Pelosi's visit to Taipei last August.
Taiwan considers itself a sovereign state. China sees it as a breakaway province that will eventually be brought under Beijing's control - by force if necessary.
On Monday, Taiwan said it had spotted another 70 warplanes and 11 ships in its surrounding waters.
A map of flight paths released by Taiwan's defence ministry showed four J-15 fighter jets to the island's east - suggesting that the Chinese military is for the first time simulating strikes from the east rather than the west where China's mainland lies.
Analysts said it was likely the jets had come from China's Shandong aircraft carrier - one of two such carriers it possesses - which is currently deployed in the western Pacific ocean, about 320km (200 miles) from Taiwan.
The Chinese military confirmed on Monday in a statement that the Shandong had "participated" in Monday's exercises. It said fighter planes loaded with live ammunition had "carried out multiple waves of simulated strikes on important targets".
Also on Monday the US sent the USS Milius, a guided-missile destroyer, through part of the South China Sea about 1,300km (800 miles) south of Taiwan.
The US said it was a freedom of navigation operation through international waters. China said the ship had "illegally intruded" into its waters.
Washington had repeatedly called for China to exercise restraint following President Tsai's meeting with Kevin McCarthy, the third most senior US government figure. Beijing meanwhile had warned the US and Taiwan of "resolute counter-measures" if Ms Tsai met Mr McCarthy.
China announced the drills after top foreign leaders it was hosting - including French President Emmanuel Macron and European Commission President Ursula von der Leyen - left the country.
The drills began on Saturday after Ms Tsai had returned from her 10-day trip to the US and Central America.
However some analysts say such military exercises may have diminishing impact over time.
"To maintain the same fear factor, [China will] have to ramp it up bigger and bigger each time as their actions will have a normalising effect after a while," said Ian Chong, a non-resident scholar at Carnegie China.
Taiwan's status has been ambiguous since 1949, when the Chinese Civil War turned in favour of the Chinese Communist Party and the country's old ruling government retreated to the island.
China's President Xi Jinping has said "reunification" with Taiwan "must be fulfilled".
China and Taiwan: The basics
- Why do China and Taiwan have poor relations? China sees the self-ruled island as a part of its territory and insists it should be unified with the mainland, by force if necessary
- How is Taiwan governed? The island has its own constitution, democratically elected leaders, and about 300,000 active troops in its armed forces
- Who recognises Taiwan? Only a few countries recognise Taiwan. Most recognise the Chinese government in Beijing instead. The US has no official ties with Taiwan but does have a law which requires it to provide the island with the means to defend itself
