A suspicious package that had been sent from Taiwan to a South Korean care home was found to have originated in China, the Taipei Mission in Korea said on Friday.

Based on information provided by Taiwan’s Customs Administration, the package was confirmed to have been sent from China and transshipped to South Korea by Taiwan’s state-run postal service Chunghwa Post Co, the mission said in a statement.

The Taipei mission said it will continue to work with South Korean authorities on the matter and share the results of the probe with the police and other agencies in the country.
