I urgently need to check this summary of a newspaper article. As I don’t know much of economy, I’d like you to check the use of words. Thank you very much.

1) Chinese economical and political influence is rising in Europe. Examples of its growth are the ownership of many city group buildings by the CIC or the purchase of thousands of m2 (square metres??) of office space.
2) This Chinese invasion scares not only Europeans but also Americans and Canadians. Politicians believe that Chinese capitals are an opportunity to solve the critical financial situation of Greece, Spain and Portugal.
3) Not only governments but also firms, like Saab, need Chinese capitals. Though China is not going to destroy the European economy, many believe that Europe (it) will be affected by the consequences of the Chinese invasion sooner than America.
4) Chinese are more likely to deal with Europe than with America, which denied China the purchase of an oil company. 5) As a matter of fact, European companies need money from China. On the other hand, Chinese companies are boosted (encouraged) to enlarge their investment-portfolio.

1) The economic and political influence of China is rising in Europe. Examples of its growth are Chinese companies' ownership of many city group buildings or their purchase of thousands of square meters of office space.

Spell out "CIC" -- you can't assume your reader will know what you're referring to -- or use the phrasing I changed this to.
Also -- there's a difference between "economic" and "economical" --

2) This Chinese invasion scares not only Europeans, but also Americans and Canadians. Politicians believe that Chinese capital is an opportunity to solve the critical financial situation of Greece, Spain, and Portugal.
In this case, you mean "capital" (all the money that is being poured into European businesses) not "capitals" (cities where governments are centered.

3) Not only governments, but also firms, such as Saab, need Chinese capital. Though China is not going to destroy the European economy, many believe that Europe will be affected by the consequences of the Chinese invasion sooner than America will.

4) Chinese capitalists are more likely to deal with Europe than with America, which denied China the purchase of an oil company.

5) As a matter of fact, European companies need money from China. On the other hand, Chinese companies are encouraged to enlarge their investment-portfolio.

1) The use of words in this summary seems to be appropriate. The sentence mentions the Chinese economical and political influence rising in Europe, giving examples of how this growth is evident through the ownership of many city group buildings by the CIC (China Investment Corporation) and the purchase of thousands of square meters of office space.

2) The use of words in this sentence is also appropriate. It states that this Chinese influence is not only a concern for Europeans but also for Americans and Canadians. The politicians believe that the Chinese capitals (meaning investments or financial resources) can be an opportunity to solve the critical financial situation of Greece, Spain, and Portugal.

3) In this sentence, the use of words could be improved for clarity. It begins by stating that not only governments but also firms like Saab, a Swedish automobile manufacturer, require Chinese capitals. It then mentions that China is not going to destroy the European economy, but many believe that Europe will be affected by the consequences of the Chinese invasion sooner than America.

4) The use of words in this sentence is clear. It highlights that Chinese are more likely to engage in deals with Europe compared to America. It gives an example of America denying China the purchase of an oil company.

5) The use of words in this sentence is appropriate. It states that European companies need money from China, and on the other hand, Chinese companies are encouraged to expand their investment portfolios.

Overall, the use of words in this summary is concise and effectively conveys the information.
