De Jong was aware the stance could leave NZF open to criticism in the wake of Winston Reid's situation during last month's World Cup qualifiers with Tahiti but was quick to stress the difference in scenarios. Reid's West Ham club boss Sam Allardyce was highly critical of Herbert and NZF for insisting Reid joined up with the All Whites even though he was injured - he didn't play either game against Tahiti.
"The window in October was for official matches whereas this window is for friendly matches, which is a tighter timeframe,'' de Jong said.
The Fifa rules around release of players for official matches is five days prior to the window, whereas friendly matches is 48 hours.
"We were able to treat Winston on arrival in New Zealand for at least four days before the match with Tahiti in Christchurch. With the China game we're talking hours rather than days,'' de Jong said.
The last of the England-based All Whites arrive in Shanghai today, with the match scheduled for 12.30am (NZT) on Thursday.
