No less than: không kém (gì)

Không kém after an adjective means "no less …, just as …": Kỹ năng mềm cũng quan trọng không kém, soft skills are just as important. To name what you compare with, add gì and the second thing: A + adjective + không kém gì + B. Hàng nội địa không kém gì hàng nhập khẩu, domestic goods are every bit as good as imports.

When the quality is clear, the adjective can be left out, as in that last example. Gì adds emphasis and is optional; so is so với (compared with) before the second thing. The phrase says B's level has been matched, not that it has been passed.

It's a stock phrase in news and reports, especially to bring in a second point: after one important factor, the writer adds that another is quan trọng không kém.

Its opposite is kém (less): Hàng này kém hơn hàng nhập, these goods are worse than imports. The không turns "less" into "no less", so don't drop it.

In everyday Saigon speech, people say không thua gì: Ngon không thua gì nhà hàng, as good as any restaurant. Cũng … như (just as … as) is the neutral way: Cũng ngon như nhà hàng.
