BEIJING, April 26 (Reuters) - China on Wednesday launched its first domestically built aircraft carrier, which will join an existing one bought second-hand from the Ukraine, amid rising tensions over North Korea and worries about Beijing's assertiveness in the South China Sea.
State media said the carrier, designed in China and built in the northeast port of Dalian, is not expected to enter service until 2020.
The announcement by the official Xinhua news agency had been well-flagged as foreign military analysts and Chinese media have for months published satellite images, photographs and news stories about the second carrier's development. China confirmed its existence in late 2015.
Its launch follows China's celebration on Sunday of the 68th birthday of the founding of the Chinese navy, and it comes amid renewed tensions between North Korea and the United States over Pyongyang's nuclear and missile programmes.
