Neither would not stop HU from joining oneworld. At present, HU and CX have same goal of preventing jetstar established in HKG. Plus HU had scaled back from its original proposal for Hong Kong significantly.

The only way HU would join oneworld is to have a clear strategy of its HUB! At this moment, HU is running an airline without a cut edge HUB! Its market share in either PEK and SHANGHAI is laughable and insignificant. For oneworld, HU does not add any value until HU could outline a strategy for oneworld to compete with Skyteam/Staralliance in Chinese corporate travel market. And to do that HU must have a sizeable market share in either Beijing or Shanghai. Currently, HU fell far behind. So HU has no advantage in negotiation with oneworld currently.

Besides that, another problem of HU is to have too many subsidiaries that heavily diluted its parent company. Its original plan to establish Gran China Airlines had failed miserably. It is all in its own making. It had made itself a company that could go bust any time. Just read any Chinese business news you would sense if any company was going to fail in China it would be HU's parent company HNA. I am certain oneworld knows this too.

However, with the new AA establish itself post merger, its codeshare with HU may speed up and we may see some changes in horizon.
