Genuinely not even a remote possibility. The Chinese navy has no where near these capabilities as they only have diesel electric submarines. They are extremely loud when running on diesel engines and only capable of going a few hundred miles when running on batteries. Furthermore, the Atlantic and Pacific coasts are littered with sonar nets and other instrumentation. It wasn't China.

The Type 094 (NATO reporting name: Jin-class; Chinese: 晋级潜艇
is a new class of ballistic missile submarine developed by the Chinese People's Liberation Army Navy. The first-of-class was constructed at Huludao Shipyard in Huludao, Liaoning Province and launched in July 2004. At least two are confirmed to have been launched.The JL-2 (巨浪-2 Ju Lang-2, Giant Wave 2) is a Chinese second generation intercontinental-range submarine-launched ballistic missile (SLBM) which has a two-stage, solid-liquid fuelled propulsion design. Accurate specifications of the new missile are hard to obtain and substantiate due to the secretive nature of the program. However, the missile is thought to be able to deliver its payload(s) up to a range of 7,200 km[3] (4,500 miles) to 8,000 km (5,000 miles) and could carry either single or multiple warheads (conventional or nuclear).
