Wales will face New Zealand, South Africa and Australia as part of the 2014 Autumn Internationals, it has been announced.
IRB's top three ranked sides will visit the Millennium Stadium along with Pacific Island nation Fiji.
The schedule will see the Springboks and the Wallabies return to Cardiff next year as part of Wales' preparation for the 2015 Rugby World Cup.
The matches against New Zealand, Australia and Fiji will be part of the IRB autumn window, with South Africa confirmed as the fourth game.
WRU Group Chief Executive Roger Lewis said: "We have consistently said if you want to be the best, you have to play the best - and the 2014 autumn schedule reconfirms that commitment.
"Next year will be ideal preparation for the squad ahead of the 2015 Rugby World Cup."
One of the Scarlets' most high-profile players is returning to the club next season, moving from Heineken Cup finalists Clermont Auvergne.
Regan King, 33, has signed a new two-year deal with the region he calls his 'spiritual rugby home'.
Scarlets Head Coach Simon Easterby said: "To have the quality and experience of a player like Regan King back in our squad next season will be a big positive for our region as a whole.
"Not only will we have secured a rugby player of real quality on the pitch who has played at the top end of European and French rugby for the past two years, but we've also gained the value of a professional who has such rounded experience which can be passed onto others.
"He's shown his inherent quality as a player in his recent performances in the Heineken Cup as well as the domestic French game and is a player any club in Europe would want in their ranks."
New Zealand-born King achieved his All Blacks cap against Wales at the Millennium Stadium in November 2002. He also played for Paris based club Stade Francais before leaving to join the Scarlets in the 2005/6 season.
He has appeared 143 times in a Scarlets shirt with 180 points.
King's last game for the Scarlets was against Cardiff Blues at home in front of a packed 11,000+ Parc y Scarlets crowd on May 6th 2011.
Wales coach Warren Gatland has been named UK Coach of the Year and High-Performance Coach of the Year at the UK Coaching Awards 2013.
Gatland led the British and Irish Lions to their first series success in sixteen years earlier this year and was presented with the award at a prestigious ceremony in London this evening.
The New Zealander joins a list of previous winners that includes Jessica Ennis-Hill's coach Toni Minichiello and England Cricket coach Andy Flower.
It is Gatland's second award within a matter of weeks after receiving the Outstanding Contribution to Rugby award at the Rugby Expo Awards last month.
Since he took over from Gareth Jenkins as Wales coach after the 2007 Rugby World Cup, Wales have won Grand Slams titles in 2008 and 2012 as well as reaching the semi-final of the 2011 Rugby World Cup.
Scrum half Mike Phillips has arrived in Paris to start his new career with Racing Metro.
Team-mate Jamie Roberts tweeted this picture of the 31-year-old, adding: 'Big moment here as @mikephillips009 signs his contract over lunch... caption competition!'
The French club confirmed on their website yesterday evening that Phillips has signed a two-and-a-half year deal.
He will be available for selection for this Saturday's Heineken Cup fixture against Harlequins.
French club Racing Metro have confirmed that Wales scrum half Mike Phillips has signed a two-and-a-half year deal to join the club.
Phillips, who's been capped 80 times for Wales and 11 for the British and Irish Lions, was sacked by another French club, Bayonne, in October, after allegedly turning up for a video analysis session under the influence of alcohol.
Wales scrum half Mike Phillips has signed for French Top 14 side Racing Metro following his sacking from Bayonne.
Racing have yet to confirm the length of the deal but have told ITV News that Phillips's transfer has been finalised and agreed by club Chairman Jacky Lorenzetti.
It is understood that Phillips will arrive in Paris tomorrow where he will meet up with his new team mates for the first time and could go straight into their squad to face Harlequins in the Heineken Cup on Saturday.
The former Ospreys player has spent the Autumn Internationals series in a state of flux since his dismissal from Bayonne for allegedly reporting for training under the influence of alcohol - a move which promoted him to initiate legal proceedings against his former employers.
It is unclear where this now leaves that action.
Phillips joins fellow Wales international Jamie Roberts and Dan Lydiate at the Paris based outfit.
George North says that Wales have to be more clinical, and accurate when they have chances, if they are to bridge the gap to the top southern hemisphere sides.
The 21-year-old scored both of Wales' tries, as they were beaten 30-26 by Australia in the final game of the autumn internationals on Saturday.
The result means Wales have lost their last 18 Tests against the southern hemisphere's big three - which also includes South Africa and New Zealand.
"The good thing is we are competing regularly with the top three, but to push on we have to be clinical and accurate when we have chances", said North - who started on the wing against Australia but finished the game at centre.
"We've shown we are competing well, but we haven't got that little edge yet. We came off the gas a little bit, and we have to be clinical. When we have them on the ropes and know we are on top of them physically, we have to push on."
Wales ended their Autumn international series with a heartbreaking defeat against the Wallabies.
It was a non-stop first half with tries from both sides.
George North put Wales in the lead with a try in the first two minutes.
The teams went into the second half with just a point between them.
Australia widened the gap in the second half with a penalty followed by a converted try by Joe Tomane.
George North scored his second 10 minutes later to make it 23-30. Rhys Priestland added another 3 points to the scoreboard with a penalty, but Wales failed to get that all-important final try which would've seen them end their Autumn series with a victory.
