The company's General Director of Mobiles and the Executive Vice-President of the corporation, Adam Zeng commented that this year the company was working to collaborate more closely with its clients throughout the world and developing products. He added that during the 2014 Mobile World Congress, which opens in Barcelona on February 24 and closes on February 27, the company would present these new devices in collaboration with Mozilla and Spanish telecommunications giant Telefonica, which is the biggest network provider in Spain and which has a massive presence in Latin America and other parts of the world.

The company will also be displaying devices for mobile hotspots and a new smartwatch.
