A multinational company has branches in may countries. Ford and Sony are examples.
Multinational companies do bring some benefits to developing countries. They provide jobs and increase the wealth of the local people. The country gains some wealth by way of taxes.
However, there are some problems as well. The jobs are often low-skilled and poorly paid. Much of the profit will go out of the country, and the company may pull out to relocate in a country where it can make a greater profit. Multinational companies are primarily interested in making profits for their shareholders. Paying wages is an expense that the company will try to reduce to as low a level as possible.
