what happened to suyin in meg 2

In Meg 2: The Trench, it is revealed that Suyin, played by Li Bingbing, died after the events of The Meg. The exact cause of her death is not revealed, and the details of what happened in the years between the two movies are not provided. A slide shown on a screen at a party in the movie confirms that Suyin died in 2021, presumably three years after the events of The Meg. Her absence is explained within the movie, but her death is barely discussed by Jonas or Meiying to help further their stories. It is unclear why Suyins character was killed off-screen, as it limits the possibility of Li Bingbing returning for future sequels.
