Japan plans to ensure that its decision to change the procedures on procuring telecom equipment, which could exclude Chinese makers, will not affect the 2 countries' relationship. Beijing is urging Japan not to exclude them.
The Japanese government decided to revise the procedures for procurement to take into account national security risks from next fiscal year, which starts in April.
The revision is aimed at preventing data leaks by cyberattacks.
The government says the change is not intended to ban specific companies. But products of Chinese telecom giants Huawei and ZTE are expected to be effectively excluded.
The United States Trump administration plans to ban the 2 makers' products from government use.
Beijing says Chinese products have posed no threat to national security.
The Japanese government plans to explain to the Chinese side through diplomatic channels that the revision is in accordance with international rules, in hopes to avoid the matter to affect improving bilateral relations.
