Yes, you need an entry permit and I think a tourist L type is enough for you. You will need the following documents, including your passport, which should valid for at least six months, a copy of your passport, a fully completed application form affixed with your recently-taken photo, the original and photocopy of your residence permit in Russia, an invitation letter from your brother, and a copy of his passport and residence permit in China (if he has it).
