Should a police caution for assault (abh) be declared?

In the above article (quoted below), you state that perhaps incidents that have not resulted in conviction (in my case a police caution) would be of no interest to a visa application. Could you confirm that is the case or in this instance would a caution be classed as a conviction in its own right and therefore should be declared? Do you know of examples where people have disclosed such an incident and resulted in a visa being denied?

I am looking to the future where I might be applying for an M (or F not sure) type for a business trip.

Any advice/guidance?

(Please don't judge :(

Naturally, you should answer questions honestly and risk failing in your application, not being admitted on arrival at the border, being expelled after entry. One hot topic is what happens if you declare that you have a criminal record. You will not be automatically denied, but if you have committed a serious crime then you may have a problem. In some countries persons may receive fixed penalty fines, perhaps for littering, or have a 'no conviction recorded' and bound over not to re-offend, or had restraining orders placed on them: these are not of concern and need not be stated on the application. Other minor offences such as are called 'summary' in Britain or 'misdemeanour' in the USA should be stated to comply with Chinese law, but it is known that many applicants do not declare them.
