China flies 103 military planes toward Taiwan in new high of activity the island calls harassment

China's military sent 103 warplanes toward Taiwan in a 24-hour period in what the island's defence ministry said Monday was a daily record in recent times.

The planes were detected between 6 a.m. on Sunday and 6 a.m. local time on Monday, the ministry said. As is customary, they turned back before reaching Taiwan.

China, which claims Taiwan as part of its territory, has conducted increasingly large military drills in the air and waters around Taiwan as tensions have grown between the two and with the United States. The U.S. is Taiwan's main supplier of arms and opposes any attempt to change Taiwan's status by force.

Taiwan's Defence Ministry said that 40 of the planes crossed the symbolic halfway point between mainland China and the island. It also reported nine naval vessels in the previous 24 hours.

The ministry called the Chinese military action "harassment" that it warned could escalate in the current tense atmosphere. "We urge the Beijing authorities to bear responsibility and immediately stop such kind of destructive military activities," it said in a statement.

CBCs David Common had exclusive access to HMCS Ottawa as it transited the China-contested Taiwan Strait to send a message that the international waters must be free and open.

China last week sent a flotilla of ships including the aircraft carrier Shandong into waters near Taiwan. The drills came shortly after the U.S. and Canada sailed warships through the Taiwan Strait, the waters that separate the island from the mainland.

The recent actions may be an attempt to sway Taiwan's presidential election in January. The ruling Democratic Progressive Party, which leans toward formal independence for the island, is anathema to the Chinese government. China favors opposition candidates who advocate working with the mainland.

Taiwan and China split in 1949 when the communists took control of China during a civil war. The losing Nationalists fled to Taiwan and set up their own government on the island.

The island is self-governing, though only a few foreign nations give it official diplomatic recognition. The U.S. among others has formal ties with China while maintaining a representative office in Taiwan
