Beijing suggested it might reimpose a ban on seafood imports from Japan after warning its citizens to avoid travel there and postponing the releases of at least two Japanese movies.

From warning tourists to halting seafood imports, China has followed a well-worn playbook in punishing Japan for Prime Minister Sanae Takaichi’s remarks linking a Taiwan conflict to her country’s security.
