Whether this is athe correct way to develop is a controversial issue.

I corrected the sentence, but on its own it doesn't make sense.

My opinion is that trades between different countries can bring positive effects.

First, buying products from around the world, like international trades are, is not only about dealing with businesses infrom other countries, but also attracts many (a lot of) new comers.

This is because people are selling not onlynot just selling goods, they are also promoting the ideas and culture inof their region, and therefore making people generate more ideas.

You can also develop this part "and therefore making people generate more ideas." to this " and encouraging others to come up with more ideas."

Thus, it improveds cultural connections and communication between nations during the process.

Of course, we should also be allergicresistant to new problems like losing cultural diversity.

I think its better to use "allergic" for physical reactions -
ex. "I'm allergic to peanuts, so I have to be really careful about what I eat."

or when using it figuratively by personal emotional or psychological aversion -
ex. " I'm allergic to conflict, so I always try to avoid it." or
"He's allergic to any form of injustice and always stands up for what's right."

But if we understand (figure out) the essence of the existence of international trade like i haveas I said before, we can find out that this is not as disadvantageous as we think it is.

In sumhort, buying the same products anywhere in the world would improve international relationships.

Meanwhile, we should be whato we want to be, and keep our own featureuniqueness.

ByIn doing so, we can make sure of thwill ensure cultural diversity and positive development between countries and businesses.

What you wrote is correct, but normally it's more common to simply talk about "trade" and not "trades".

First, bBuying products from around the world likethrough international trades areis not only about dealing with businesses in other countries, but also attracts a lot of new comersleads to economic growth.

I wasn't entirely sure what you meant by "new comers", I changed it to economic growth instead. To me "new comers" is a bit vague.

This is because people are selling not only selling goods, but they are also promoting the ideas and culture inof their region, and therefor. Thus, making people generate more ideas.more open minded.

There was a spelling mistake in "therefor", and introduced an article because you're referring to something specific. In this case, "the ideas and culture" of a region.

Thus, it improveds cultural connection and communication between nations during the process.

I think it makes more sense for it to be in the present tense because you're referring to a process that is ongoing.

Moreover, the availability tof buying products from around the world increases cultural trust.

To be specific, oOur society is based on credit, which was established by countless deals between people.

So, things like this actuallyHence, international trade develops positive relations acrossbetween countries.

"Things" is very vague.

Of course, we should also be allergicdverse to new problems like losing cultural diversity.

"Allergic" is normally in reference to something related to food or pollen for example.

But if we figure out the essence of the existence of international trade like i have said before, we can find out that thisHowever, the essence of international trade is not as disadvantageous as we think it is.

Besides, the problem is merely a possibility.Losing cultural diversity is a problem, but the advantages gained from international trade outweigh the disadvantages.

I don't think it makes sense to say that the problem "is merely a possibility". In my opinion, the negative impacts of international trade are real and not merely a possibility.

In sum, buying same products anywhere infrom around the world wouldill improve international relationships.

I'm assuming you meant different products. Changed "would" to "will" because it's more affirmative.

Meanwhile, we should be what we want to be, and keep our own features.However, we still need to keep our cultural identity and hold onto the things that makes us unique.

By doing so we can make sure of theHence, we need to find a way to hold onto cultural diversity and posiat the same tivme development positive relationships between countries and international businesses.

Countries are becoming more and more similar these days.

Or "are becoming increasingly similar".

Whetherile this is a correct way to develop, it is a controversial issue.
