From the official site of the Foreign Affairs Ministry of the Russian Federation:
Documents:
Tourist visa:
- Для граждан третьих стран (не граждане КНР): копия визы или документа, дающего право на непрерывное нахождение в стране пребывания на период более 90 дней.
Free translation:
For non-citizens of China, a copy of visa or an another document which enables you to stay for more than 90 consecutive days.
So, just a visa is ok.
Note, the Russian Embassy in China recommends to not apply for visa directly but to use the Russian Visa Center in Beijing: http://www.russiavisa-china.cn/English/Tourist.html
