Here’s a couple of links:
VWRP - Vanguard FTSE All World GBP Accumulation (launched July 2019)
VWRL - Vanguard FTSE All World GBP Income - launched 2012 if you would like to see a longer track record.
If you look under documents/factsheet - you will note it holds over 3000 stocks globally, so its a really diversified fund that will return a good average of the global stock markets.
It also shows you market allocation, and since you mentioned China, 3.9% of the ETF is invested in Chinese stocks.
The Morningstar website has a wealth of information, and even allows you to compare different ETFs, Funds and Investment Trusts against each other.
That being said, past performance is not a guarantee of future performance and so on.
You might also find this article interesting as well, its not the article I was looking for, but it is reasonably well written.
