South Korea and China have agreed to expand technical cooperation to jointly develop faster, more powerful mobile phones on which users can watch movies, the Korean Ministry of Information and Communication said Wednesday.

At the third round of meeting by the two countries Tuesday in Shanghai, officials from the two countries agreed to support the research of fourth-generation (4G) wireless communications system, the Ministry said.

The 4G system is still uncertain, but industry observers said the new technology will allow users to watch movies with a sharp, high-quality picture on their handsets. The Ministry did not provide details about the agreement. The next and fourth meeting will be held in Seoul next year, it added.
