Monday's result sent New Zealand (0-1-2) home while China (1-1-1) advanced to the round of 16 as the second-place team behind Canada in Group A. The Kiwis needed a win to survive.
A jubilant China coach Hao Wei tried to shake hands with New Zealand's Tony Readings as he went past the New Zealand dugout after the final whistle but the Kiwi coach just shook his head in refusal.
Readings was upset at an incident late in the game when Hao appeared to get in the way on the sidelines as New Zealand's Roa Percival tried to throw the ball in and keep the play going.
Hao was dismissed from the technical area by the referee for his actions.
"It's just something that I don't agree with," Readings said later through an interpreter of Hao's actions.
"I would never go out of my way to do that to an opposition player. You've just got to let the players on the pitch do the business. Whilst we want to influence things, we should always be backstage not onstage."
The English-born Readings prefaced his comments by saying he had always had a good relationship with Hao in the past and expected the two of them would get on again in the future.
Readings also said he had expected gamesmanship given what was on the line and was pleased by the way his team handled it.
The New Zealand coach said he was proud of his players and the way they had performed despite the tournament results.
"We've proved we can more than compete with teams at this level," he said.Suggest a correction
