Fiji coach John McKee says his side's narrow 17-13 defeat to Wales was "frustrating".
The Pacific Island team played most of the second half with 14 men, but Nemani Nadolo's interception try gave Wales a late fright.

"We're disappointed for losing. We came here to try to win the game," said McKee.
"We probably didn't impose ourselves as much as we would have liked to in the first half.
"In the second half, it was a tremendously gutsy performance by a team with 14 players for most of the half.
"Firstly to withstand the Welsh pressure and then to come up with a try to narrow the game at the end."

Warren Gatland was frustrated by some decisions from referee Pascal Gauzere, but McKee felt his side were hard done by too.
"It's interesting that he's complaining. I felt sometimes we didn't get the bounce of the ball," he said.
"There were 50-50 decisions which didn't seem to go our way but that's the game sometimes."
Fiji meet Wales again in next year's World Cup pool stage and McKee promises Gatland's men another tough match.
"We've been together for a short time and by the Rugby World Cup this group will be stronger," said the former Australia academy coach.
"The little things letting us down are our continuity, our connection and our defence sometimes.
"But that gets better and better the more time you're together.
"Wales will be better next year as well. There are things we need to work on to really capitalise on opportunities against teams such as Wales."
Wales' next match is against world champions New Zealand on Saturday, 22 November.
"The All Blacks are playing very good rugby at the moment, so it will be a tough encounter," said McKee.
