From “hola” to “au revoir,” learning a foreign language can help corporate employees — especially those who travel internationally — succeed in their jobs and achieve their goals. Learning a language abroad for business can be a lot easier since there is opportunity for day-to-day conversation as well as at-home study.

Studies show that people who can speak a second language make 10 to 15 percent more in salary than those who don’t. Being bilingual can also help you be more effective in your career as a globetrotting business person. Being able to talk with people in their language will impress clients and make it easier to communicate. It’s also a sign of respect that is sure to give you a leg up on the competition.

Of course, the best foreign language to learn varies from person to person. If your work takes you to France a lot, learning a language abroad during your time in France is just as important as home-study. That aside, here are the top 10 languages to learn that can help you improve communications and relations with international contacts.

1. Mandarin Chinese

There are lots of reasons to learn Mandarin Chinese. First, nearly 1 billion people speak it, and in addition to China, it’s the language of Indonesia, Thailand, Malaysia, Singapore, and Brunei, all of which are growing as economic forces.

Second, despite China’s troublesome stock market, the country remains a global force in manufacturing, and countries throughout the world have investments there. Anyone working in international business and manufacturing would greatly benefit from learning Mandarin Chinese. Chances are that any global company you work for has some dealings with the country. Another factor to consider is that relatively few people in Chinese speak English.

2. Spanish

About 20 countries are Spanish-speaking, including many in South America, where many companies are discovering opportunities for business growth because of factors including its proximity to the United States, natural resources and a growing economy. Spanish-speaking countries include Argentina, Venezuela, and Ecuador.

There’s also Mexico, which is drawing investors with its free market economy and increasing trade with the United States. Speaking Spanish also can help improve your business within the U.S., as it the second-most language spoken there.

3. Arabic

As the official language of many Middle Eastern countries where business opportunities are growing, learning to speak Arabic can be a big plus.

Arabic is the official language of Saudi Arabia, which has the strongest economy in the Middle East. While some have predicted that lower oil prices could hurt Saudi Arabia’s economy, that hasn’t been the case so far. In fact, U.S. exports to Saudi Arabia totaled $19 billion in 2015, a record high.

Other key countries where Arabic is spoken include Jordan, a wealthy nation in the Middle East that has a free-trade agreement with the United States, and Israel, which has two official languages: Arabic and Hebrew.

4. Russian

Opportunities for investments in business and real estate abound, and many of those wealthy Russian people do not speak English. Russian also is the official language such countries as Belarus, Kazakhstan, Krygystan, and Tajikstan. It’s also a common second language in several countries, including Armenia, Bulgaria, Finland, Latvia and Lithuania.

5. Japanese

Japan is one of the biggest purchasers of American products, and is a dominant player in the technology industry. The country is at the forefront of robotics, employing more than 250,000 people in the industry, which some people think could have huge influences on business and society.

Japan also invests in countries around the world, and has a strong economy with 3.1 percent unemployment, and solid GDP growth.

6. Portuguese

This language is similar to Spanish, if not as commonly spoken. It is the language of Brazil, with its population of more than 200 million. The country is growing in population, 62 percent of its residents are 29 or younger, and it’s growing in wealth.

The world will be watching Brazil during the upcoming Summer Olympics. Anyone interested in creating connections with a large, young population with many business professionals will do themself a favor by learning Portuguese, which also is spoken in Portugal, Angola, Macau, and other countries.

7. French

French is an official language in various countries in Europe (France, of course, but also Belgium, Switzerland and Luxembourg), Africa (Cameroon, Mali, Madagascar and many others), and North America (Canada).

French was the common “international language” for business and diplomacy for many years, and it remains the official language of the United Nations, NATA, the World Trade Organization, and the International Olympic Committee. While English has emerged as a more common language, many companies around the world do business in French.

8. Hindi

Business relations between the United States and India has grown over the past 30 years, with the two countries trading $1 billion in goods and services on an annual basis, up from $100 million in 1985.

Different languages are spoken in the country’s different regions. You’ll likely speak English when talking with contacts from India, but learning Hindi, which is the most common first language in the country and a common second language, could be a big advantage when doing business in India.

9. German

Germany has one of the biggest, strongest and most stable economies in the European Union. German is the most widely spoken language in Europe, with 16 percent of Europeans naming German as their first language.

Germany is one of the world’s top three exporters (behind the U.S. and China), most notably in automobiles, machinery and chemical products. It also appears primed for the future, as it is a leader in green energy advances, and its laws allow foreign investors to establish and invest in its companies.

10. Bengali

The second-most popular language in India, Bengali is spoken in the Bengal region, which includes Bangladesh, West Bengal, Tripura and Assam. About 250 million speak it in India, with about 300 million speaking it throughout the world.

Knowing Bengali can help improve business relations in a key region of India, which is a growing market for goods and services. With a growing middle class comes a growing need for consumer goods and infrastructure, creating a variety of business opportunities.
