Their economic relationship, too, seems to be progressing. Last May, shortly after the annexation of Crimea, Russia announced a $400 billion deal to supply 38 billion cubic meters (bcm) of gas to China annually for 30 years, beginning in 2019.
它们的经济关系也在前进。去年5月，即在吞并克里米亚后不久，俄罗斯宣布与中国签署了一份为期30年、价值4,000亿美元的协议，从2019年开始每年向中国提供380亿立方米天然气。
