"We battled hard and that was a big win for us. We got some momentum, even throughout that game it felt like we picked up momentum as the game went on."
Elsewhere, Italy hammered South Korea 7-1 while Russia saw off the Netherlands 8-5.
Meanwhile, 2014 World Champions Norway got their campaign underway with a nail-biting 7-6 victory over Denmark, which saw Norwegian skip Steffan Walstad spare his blushes in the extra end, having jammed a stone in the tenth end to give the Danish team a steal.
The event is the first in the qualification process for the 2022 Winter Olympics, with the top six placed nations qualifying directly for Beijing.
