What do I have to make sure my country has before it is in a position to help assist other countries with the rights and economy?Language
I don't know that there is any kind of rule about this. Basically, all your country has to do is have enough money and power.
It is not as if there is some threshold of money or power that you have to reach and then you are allowed to help other countries out -- there's no set limit for when you can get your "license" to do this.
All you have to have to help economically is more money than the other country. China is relatively poor on a per capita basis but it is helping African countries, for example.
On rights, all you need is power and the belief that your form of government is better than everyone else's so that you deserve to "help."

Genuine moral authority and open government.
In international politics the best way for a country to help other countries is to develop mutual cooperative relationship with them. And for doing this there are no precondition required. Whatever be the condition of a country, cooperation will enable it to help other countries as well as itself.
I strongly disagree with the the concept of powerful countries adopting a paternalistic attitude towards the not so powerful ones, pretending to dole out economic assistance and trying to improve their government under the arrogant belief that their form of government is better than everyone else's".
No powerful country has ever been interested in sharing its power with others, and no rich country has ever been satisfied with the riches it already has. A rich and powerful country helps a poorer and weaker country to primarily promote its own interest rather than that of the country receiving the help.
Take, for example, opposition that exists in USA to outsourcing of some business activities to developing countries. In spite of the fact that outsourcing is done at wages a fraction of rated prevalent in the USA, and that it helps people in USA to buy things at lower prices, many people in US grudge the meager earnings of people outside USA.
