According to the Trademark Law, without the permission of the trademark registrant, using a trademark similar to its registered trademark on the same commodity or using a trademark identical to or similar to its registered trademark on similar commodities is likely to cause confusion and will constitute infringement. And the other party produces different kinds of products, so it doesn't count.
When registering a trademark, only search will be considered in the trademark category used. If you have the same category of use and already have the same or similar registered trademark, you can't register it. If you use it, it will be regarded as infringement.
The Trademark Law stipulates that the unauthorized use of a trademark identical with or similar to a well-known trademark registered in China may mislead the public and harm the interests of well-known trademark registrants. So if you are a well-known trademark, it is infringement.
