The FTA is specifically focused on eliminating tarrifs on the trade of goods and services, not on lowering investment checks, so I am not sure how you are making that connection. The list of goods and their incrementally reducing tarrifs are scheduled here: https://www.dfat.gov.au/sites/default/files/chafta-explanatory-schedule-of-chinese-tariff-commitments-non-official.xlsx

"ChAFTA will increase opportunities by eliminating tariffs on the vast majority of trade in goods between Australia and China. This benefits Australian businesses that export Australian goods to China or import Chinese goods for sale in Australia."

An example of how it impacts services:
"China has removed the minimum RMB100 million working capital requirements for branches of Australian banks operating as subsidiaries in China"
