The "big four" IT companies in China are referred to collectively as BATH — an acronym made from the initials of search engine Baidu, shopping site Alibaba, chat app and game producer Tencent and hardware manufacturer Huawei.

Aggressive moves by the U.S. government to exclude Huawei, which has been pitching its next-generation 5G high-speed mobile communications, are being closely watched by Japan's media.
