彭博社上星期委托著名的半导体调查公司 TechInsights 拆解了一台中国华为新上市的 Mate 60 Pro手机，证实里头使用了中国国产的七纳米芯片。这个消息震撼美国，因为这表明在美国的严厉制裁与限制之下，中国只用了三年时间就能自己生产出七纳米高端芯片，突破了美国的科技封锁。

一个星期后，华为又宣布预售另两款新手机，经过测试都有5G的功能，证明中国已经能大量生产高端的芯片。

中国是否真的已经冲破了被美国科技卡脖子的困境？这对中国的贸易军事发展以及国际关系意味着什么？中美科技战的下一步又会如何发展？

这期的早报播客《东谈西论》，听《联合早报》副总编辑韩咏红与华中科技大学教授、光谷自贸区研究院院长陈波及新加坡南洋理工大学教授、毕盛资产管理有限公司创始成员兼副主席（中国）陈光炎博士详细解析。

Chinese mobile phone company Huawei unveiled its latest Mate 60 Pro. According to a teardown report by analysis firm TechInsights, Huawei Technologies and China's top chipmaker Semiconductor Manufacturing International Corp (SMIC) have built an advanced 7-nanometre processor to power its latest smartphone.

The 7nm chip represents a breakthrough in China’s chipmaking capability. It was previously believed that the best China could achieve was about 14nm.

Has China managed to circumvent US restrictions? What are the implications of Huawei’s new chip on China-US relations? Where is China-US tech war heading？
