Cambodian officials were among a group of delegates from 21 nations who attended a conference on climate change Monday in Bangladesh. The conference, which was limited to poor countries from Asia and Africa that are especially vulnerable to global warming, was geared towards developing a common set of resolutions ahead of the larger UN summit on the environment, to be held in Copenhagen, Denmark, this December. The delegates called on developed nations with high carbon emission levels to contribute more to the fight against global warming, and also discussed domestic strategies to combat the problem.
