China is showing the world its great resolve in the global climate campaign with concrete and self-motivated efforts as well as serious commitment. At the opening ceremony of the Paris climate summit, Chinese President Xi Jinping restated China's plan made in June to cut its carbon emissions  per unit of GDP by 60-65 percent from 2005 levels by 2030, and increase non-fossil fuel sources in primary energy consumption to about 20 percent.  With a large population, China is facing increasing resource limits, severe environmental pollution and a worsening ecosystem, and its citizens are also becoming increasingly aware of environmental problems. Suffering environmental problems and seeing the efforts as important to transforming its economic growth pattern, the country has much at risk if climate change is left unattended.  Actually, climate change efforts are already included in China's medium- and long-term program of economic and social development, and ecological efforts are the clear characteristics in China's 13th Five-Year Plan (2016-2020).  Although it is and will be a developing country for a long time to come, China has been actively involved in the global campaign against climate change, now topping the world in terms of energy conservation and use of new and renewable energies.  However, China's development rights need to be respected. It is unfair to overstress China's status as one of the world's largest greenhouse gas emitters and regard it as the major part of responsibilities in the global fight against climate change.
