The help China gives Russia in the war in Ukraine has long caused dismay(沮丧，失望) in Western countries. Exports of ostensibly(表面上) civilian components such as engines and electronics end up in drones and other weapons that kill Ukrainian soldiers and civilians, abetting Russia’s war of attrition(消耗战). Yet recently it is the other end of this trade that has stirred alarm in Western capitals. China appears to be receiving training, intelligence and advanced military technology from Russia. That could give China an edge in a future war over Taiwan, tilting the balance of power at the opposite extreme of Eurasia.(这可能会让中国在未来台海战争中获得优势，从而在欧亚大陆另一端改变力量平衡。)
中国在乌克兰战争中向俄罗斯提供的帮助长期以来令西方国家感到沮丧。发动机和电子设备等表面上属于民用部件的出口最终被用于杀害乌克兰士兵和平民的无人机及其他武器，助长了俄罗斯的消耗战。然而，最近正是这种贸易的另一端引起了西方各国首都的警觉。中国似乎正在从俄罗斯接收训练、情报和先进军事技术。这可能会让中国在未来可能爆发的台海战争中获得优势，从而在欧亚大陆的另一端改变力量平衡。
Since 2024 Chinese soldiers have undergone(经历，接受) training in drone and urban combat at a military complex near the city of Volgograd in south-west Russia, people briefed(被通报，被告知) on European intelligence tell The Economist. That complex is used regularly by Russia’s 8th Army, the backbone of Russian operations in eastern Ukraine. Its tactics are hardly a model to emulate(几乎不值得效仿). Yet China has not fought a war since a brief border conflict with Vietnam in 1979. To conquer Taiwan, it needs access to the latest battlefield lessons and data to compensate(补偿，弥补) for its lack of combat experience.
据知情欧洲情报人士向《经济学人》透露，自2024年以来，中国士兵已在俄罗斯西南部伏尔加格勒市附近的一个军事基地接受无人机和城市战训练。该基地是俄罗斯第8集团军（俄军在乌克兰东部作战的骨干力量）的常用驻地。其战术几乎不值得效仿。然而，中国自1979年与越南发生短暂边境冲突以来，再未打过仗。要征服台湾，它需要获取最新的战场经验和数据，以弥补其缺乏实战经验的短板。
It also has more leverage(筹码，影响力) now to obtain some of the best military technology that the Kremlin was previously unwilling to share. American and allied officials believe that may include upgrades to China’s air- and missile-defence systems. They also fear that Russia is helping China produce stealthier(更隐蔽的) nuclear submarines. China sees these vessels as critical for any war over Taiwan, which could escalate(升级，加剧) into a nuclear confrontation with America.
中国现在也有更大的筹码来获取克里姆林宫此前不愿分享的一些最先进的军事技术。美国及其盟友的官员认为，这可能包括对中国防空和导弹防御系统的升级。他们还担心俄罗斯正在帮助中国建造更隐蔽的核潜艇。中国认为这些舰艇对任何可能升级为与美国核对抗的台海战争至关重要。
