STOCKHOLM: Swedish singer Zara Larsson said Tuesday that she had ended her collaboration with China's Huawei to promote its smartphones, saying China "is not a nice state," but the firm responded that the deal had always been limited in time and had ended "as agreed".

Speaking with broadcaster TV4, Larsson, whose greatest hits have been streamed over five billion times according to the broadcaster, said the collaboration with Huawei had ended a few months ago.

"If I now look back it wasn't, from a professional but also a personal perspective, the smartest deal I've done," the 22-year-old singer said. "It's not something I stand behind," she added.
