Hello, 


I am not sure whether these sentences make sense in term of grammar and semantics.

Can you give me a hand with checking them

Thank you for your help.

1. In order to cultivate young people’s leadership, it is as important for them to learn how to compete for others as it is for them to gain a sense of cooperation.



2. Nowadays, to solve a range of problems, such as war, environmental pollution, natural disasters, epidemic diseases, energy shortage and so forth countries all over the world encounter, their society should infuse their young people with the spirit of cooperation. After all, it is only when countries understand how to cooperate with each other that they can tackle the above problems quickly and easily.



3. America cooperated with Russia, South Korea, China and Japan to put international pressure on North Korea’s nuclear ambition.

You can also say: "the aforementioned problems" or "the aforesaid problems".
