“二十国集团”怎么翻译？

原文：当前，世界经济出现向好势头，有关国际组织预计，今年世界经济有望增长3.5%。这是近年来最好的经济形势。有这样的局面，同二十国集团的努力分不开。同时，世界经济中的深层次问题尚未解决，仍然面临诸多不稳定不确定因素。

官方译文：The global economy is showing signs of moving in the right direction. The related international organizations forecast that it will grow by 3.5 percent this year, the best performance that we have seen in several years. This would not be possible without the efforts of the G20. On the other hand, the global economy is still plagued by deep-seated problems and faces many uncertainties and destabilizing factors.
