The chemist who helped create the magic sauce behind Juul, Xing Chenyue, unveiled the product of her new startup Myst Labs this week after two years of development: electronic cigarette alternatives designed for China’s 350 million smokers, the world’s biggest smoking population.

This new contender makes for a potentially heated battlefield given that Juul will reportedly enter China soon. TechCrunch has reached out to Juul about its expansion, but has not heard back at the time of writing.
