Item 1?
What does the first item on the list actually mean?
"1. Approach data security with an objective and rational attitude, and maintain an open, secure and stable global supply chain"
As for the PRC promoting ICT security, well, everyone is in favour of that, but who believes that any state actually practices what they preach on this subject? Respecting other states' sovereignty is all very well, until you reckon that there is information they have which would protect your sovereignty. The USA is quite adamant in declining to join the ICC, because it would mean USA soldiers could be prosecuted for 'war crimes' in a court outside the control of the USA Supreme Court.
I can only assume it is some sort of PR event by the Chinese until they prosecute a Chinese company for helping the Chinese Communist Party obtain data from a foreign entity without the foreign state's approval.
