It is the definition on Cooperation in Wikipedia:
"Cooperation (sometimes written as co-operation) is the process of groups of organisms working or acting together for common, mutual, or some underlying benefit, as opposed to working in competition for selfish benefit. Many animal and plant species cooperate both with other members of their own species and with members of other species"
Here is how Chinese Leader Xi said during his speech at the G 20 Leaders' Summit:
"Going forward, win-win cooperation is the only choice for us, be it in good times or bad. This is dictated by the law of economics. and it is in keeping with the development of human history." -------Xi Jinping
