Weren’t a lot of the passengers Chinese? China should make a contribution to the recovery effort.
To be fair, both China and Malaysia have paid a fair share of the search costs up until earlier this year when it was finally stopped by mutual agreement - but restarting the search now would almost certainly be on Australia.

Our best bet may be to ask for an agreement to share the costs if we actually find something - there’s a good chance they might agree to that. But not just on new speculation.
