Virtually all plants being built in China today are third-gen evolutions of proven second-gen PWRs, themselves very safe.
Hiding a Chernobyl-scale nuclear disaster would be far more difficult today; even in China, total news blackouts are a lot more difficult to pull off than they used to be. And the designs in use are inherently a lot safer and more conservative than the RBMK type (which was really pretty innovative and impressive for the time, if you ignore the unfortunate tendency to explode, but certainly _not_ conservative).
