[ Grammar ] important "to do" something or important "to doing" something
It's confusing. I have learned that " important to do something" is right.

However, I read some articles from The Guardian : " It will also give due consideration to adaptation to climate change, which is important to developing countries. "

--------

Q1: Could we use "which is important ""to develop"" countries" here ?

Q2: the meanings of " important to do " and " important to doing " are same ?

Q3: When or How to use " adjective + preposition + gerund " and " adjective + infinitive " of the word " important " ?

Thank you :)

Answer

Developing is not a verb there. It is an adjective, which describes the countries...
The 'which' changes the grammar of the sentence.
....(noun clause), which is important to (noun clause).
What you learned is  "it is important to (verb clause).

Answer

Here, I suggest ''developing countries'' ought to be treated as a whole and thus maybe it is not right to consider ''developing'' as a verb followed by ''is important to''. Rather, it actually describes a characteristic of a certain country, for there are developed countries as well as developing countries in the world, which is a common belief.
