What language must I use for a patent application in China?

Any document submitted under the Chinese Patent Law and its Implementing Regulations must be in Chinese. Patent Cooperation Treaty (PCT) applications can be filed in either Chinese or English. However, you must submit a Chinese translation of the application within 30 months of the priority date (extendible to 32 months subject to payment of a surcharge).
