Air conditioners for trains from Mitsubishi Electric Corp. that may not have gone through proper inspection before shipment have been exported to about 15 countries including the United States, the United Kingdom and Germany, company officials said Wednesday.

The Japanese electronics conglomerate has exported a total of 15,800 such air conditioners, although there are no problems with their safety or performance, the officials said.

The Tokyo-based company admitted last week that about 84,600 air conditioners with falsified inspection data were delivered to some 80 companies between 1985 and 2020, of which some 20% went to clients overseas, either directly or via different Japanese companies, they said.
