Does somebody know which is the procedure to submit a Third Party Observation at SIPO (China)?
On its website there isn't any information related to TPOs.

I submitted this question at the EPO Asian Info Helpdesk and in a nutshell, if you are not familiar with the Chinese language you need a chinese attorney.
The legal basis for TPO's in China is Rule 48 of the Implementing Regulations. You need to file them in Chinese as per Rule 3 (but not the documents you might be referring to) and apparently it is not possible online, rather you have to adress it to SIPO directly.
If I ever come to the point of having serious reasons to file TPO's with the SIPO, I will simply gather all relevant prior art documents and sent them to SIPO, along with a google-translated short passage like "please find enclosed relevant prior art in respect of XXXXX patent application". And I will see what happens!
As apparently no one has found an answer yet, I'll make one with what we have. Feel free to edit in anything you find.
Rule 48 from the "Rules for the Implementation of the Patent Law of the People's Republic of China" (http://english.sipo.gov.cn/laws/lawsregulations/201403/t20140331_925757.html) allows third party observations until the notification of the grant.
http://www.managingip.com/Article/3440424/How-to-make-effective-third-party-observations.html This article states that there is an electronic form, which I couldn't find, so maybe it exists only in Chinese. If one wants to add documents to the third party observations they have to made in paper form anyways.

Further information might be available by contacting the EPO China helpdesk (https://www.epo.org/searching-for-patents/helpful-resources/asian/china/faq.html). I have contacted them once on another issue and they were very helpful!
For PCT applications, as far as I know, it is enough to send the observations to the WIPO and they will send them to the relevant national authorities.
