China's first domestically-built aircraft carrier Shandong sailed through the Taiwan Strait on Thursday, reported Global Times quoting various Taiwan media.

This marks the second time Shandong sailed across the strait. It was last there on November 17.

The new aircraft carrier, named after eastern China's Shandong Province, was delivered to the People's Liberation Army (PLA) Navy and placed in active service last Tuesday, with Chinese President Xi Jinping attending its commissioning ceremony. 

Experts say the vessel may be conducting its final "test run."
