Bin Li is as close as China may have come to cloning Elon Musk. 

主句和比较从句共用了一个介词短语：to cloning Elon Musk。这是承后省略。

正常语序为：

Bin Li is as close to cloning Elon Musk as China may have come （to cloning Elon Musk）. 

主要结构：be close to doing ：最接近做某事

比较结构：He is as close to doing as China is （may have come 替换 is）

字面：李斌模仿制造伊隆·马斯克车，跟中国可能做到的距离一样近。

引申：如果说中国可能在模仿制造伊隆·马斯克车，那么李斌是最接近的。
