Do I Need to Speak the Language to Do Business in Indonesia, Malaysia, Vietnam?
You are considering Indonesia. Your product fits the market. The numbers look good. Then someone asks, "Do you speak Bahasa?"
You do not. Should you learn it? Can you hire someone who does? Or can you just get by with English?
This question stops more businesses than it should. The answer is simpler than you think, but it depends entirely on what kind of business you are running and who you are selling to.
The Short Answer: You Do Not Need to Speak the Language, But You Need Someone Who Does
If you are a business owner or senior executive trying to expand into Indonesia, Malaysia, or Vietnam, you do not personally need to speak the local language. But someone in your operation absolutely must.
This is not about being polite or showing respect (although that helps). It is about practical business reality. Contracts need to be in the local language. Government filings require local language documentation. Negotiations, customer complaints, and supplier issues all happen in the local language, even if the initial sales conversation was in English.
You can run the strategy and make the big decisions in English. But the day-to-day execution requires local language fluency.
When English Is Enough
There are situations where English will get you 80% of the way there.
Singapore. Roughly 80% of the population speaks English fluently. Business is conducted in English. Contracts are in English. Government filings can be done in English. If your entire Asia strategy is Singapore only, you do not need to worry about language barriers.
Malaysia (corporate sector). If you are selling to large corporations, multinational subsidiaries, or government-linked companies, English is the working language. Senior executives, procurement teams, and IT departments at these companies operate in English. You will not have significant language issues.
The Philippines. Over 90% of the population speaks English. The country has become a premier outsourcing destination specifically because of its English proficiency. Business is conducted almost entirely in English.
B2B tech and enterprise sales across the region. If you are selling enterprise software, industrial equipment, or high-value B2B solutions to large companies, the decision-makers usually speak English. They went to universities where English was the medium of instruction. They work for companies where English is the corporate language.
In these scenarios, you can close deals, negotiate contracts, and manage relationships entirely in English.
When English Is Not Enough
The problem starts when you move outside the English-speaking corporate bubble.
Indonesia (outside of Jakarta's corporate sector). Indonesia has 280 million people. Only about 3% are ethnic Chinese, and English proficiency outside of multinational companies is low. If you are selling to local distributors, mid-sized manufacturers, or businesses outside the top-tier corporate world, you need Bahasa Indonesia.
Even in Jakarta, once you get past the initial meeting with the CEO who speaks perfect English, you will be dealing with operations managers, warehouse staff, and finance teams who do not. That is where things break down.
Malaysia (SMEs and local distributors). Outside of the big corporations, many Malaysian businesses operate in Malay or Mandarin. If you are working with distributors, retailers, or smaller partners, English might work for the first meeting, but everything after that (contract negotiations, problem-solving, day-to-day coordination) will require Malay or Mandarin.
Vietnam. English proficiency in Vietnam is growing, but it is still limited outside of Hanoi and Ho Chi Minh City's business districts. If you are selling to local companies, government entities, or working with Vietnamese distributors, you need Vietnamese speakers on your team.
Thailand. English proficiency is lower than most people expect. Even in Bangkok, many business professionals struggle with English beyond basic conversation. If you are doing anything more complex than tourism or surface-level business development, you need Thai language capability.
Any business that involves government, regulation, or legal processes. In most Southeast Asian countries, all official documentation must be in the local language. Employment contracts, company registration documents, tax filings, permits, and licences all require local language versions. You cannot get around this.
The Real Problem Is Not Meetings, It Is Operations
Here is what actually happens when you try to operate without local language support.
The initial meetings go fine. The distributor's CEO speaks English. You agree on terms. You shake hands. Everything feels smooth.
Then problems start. Your shipment gets stuck in customs. The person handling it does not speak English. Your distributor tries to explain the issue to you in broken English, but you cannot understand the actual problem. It takes three weeks to resolve something that should have taken three days.
Or your contract needs to be amended. The legal team on the other side only works in the local language. You hire a translator, but the nuances get lost. What you think you agreed to is not what the contract actually says.
Or a customer has a complaint. Your local partner tries to handle it, but they need guidance from you. The problem is technical. Explaining it in English takes 30 minutes and still leaves confusion. In the local language, it would take five minutes.
These are not rare edge cases. This is daily reality when you operate across language barriers.
What Actually Works: Hire Local Capability
The businesses that succeed in non-English markets do one of three things.
They hire a local country manager or sales lead who is bilingual. This person speaks English well enough to report back to headquarters and communicate strategy. But they also speak the local language fluently, so they can handle negotiations, contracts, government filings, and operational issues without translation delays.
This is the most common and most effective solution. You do not learn Vietnamese. You hire someone who speaks Vietnamese and English, and you trust them to execute on the ground.
They partner with a local distributor or agent who handles everything. You manage the relationship in English at the strategic level. The local partner handles all local language execution (sales, contracts, logistics, customer support). This works if you find a trustworthy partner who is genuinely capable.
The risk is that you are completely dependent on them. If they are lying to you, hiding information, or underperforming, it is much harder to detect when you cannot speak the language yourself.
They work with local consultants or advisors who bridge the gap. For specific projects (market entry, regulatory compliance, contract negotiation), they hire local advisors who can handle the language and cultural nuances. This is more expensive than hiring full-time staff, but it works for early-stage exploration before you commit to full operations.
Should You Learn the Language Yourself?
If you are planning a sustained career in Asia, especially in a specific country, learning the language is a major advantage.
The question is whether it is worth the time investment. Learning Bahasa Indonesia to conversational business fluency takes roughly 1,000 to 1,500 hours of study. That is six months to a year of dedicated effort.
If Indonesia is going to be your primary market for the next decade, that investment makes sense. You will build better relationships, catch problems earlier, and avoid being dependent on translators or intermediaries.
But if you are a CEO managing multiple markets and your role is strategy rather than day-to-day operations, your time is better spent hiring local talent who already speak the language.
One exception: learning basic conversational phrases in the local language is always worth it. Being able to greet people, say thank you, and make small talk in their language builds rapport and shows respect. You do not need fluency for that. Fifty hours of study gets you there.
Which Language Should You Prioritise?
If you are going to invest in learning a language, or if you are deciding which language capability to hire for, here is how to think about it.
Mandarin Chinese. There are large Chinese populations across Southeast Asia (76% in Singapore, 34% in Malaysia, 14% in Thailand, 3% in Indonesia). If you are selling to Chinese-owned businesses or working with ethnic Chinese distributors and partners, Mandarin helps. It is particularly valuable in Malaysia and Singapore.
Bahasa Indonesia. Indonesia is the largest market in Southeast Asia by population. If your expansion strategy prioritises Indonesia, Bahasa Indonesia is the most valuable language. It is also relatively easy to learn compared to tonal languages like Vietnamese or Thai.
Vietnamese. If Vietnam is a core market for you, Vietnamese is essential. English proficiency is lower than in other Southeast Asian countries, so you need local language capability more urgently.
Thai. Thailand has a large economy but lower English proficiency than neighbours. If you are serious about Thailand, Thai language capability matters.
Malay. Useful in Malaysia, though many business contexts operate in English or Mandarin. Less critical unless you are targeting Malaysian SMEs or government sectors.
The Multilingual Advantage
Businesses operating across multiple Southeast Asian countries are increasingly hiring multilingual staff or building multilingual teams.
Why? Because the region is linguistically diverse, and relying on English alone limits your market reach. Companies that can operate in English, Mandarin, Bahasa Indonesia, and one or two other local languages have a significant competitive advantage.
This does not mean every employee needs to speak five languages. It means your team collectively covers the languages you need. Your Singapore office handles English and Mandarin. Your Jakarta office handles Bahasa Indonesia. Your Hanoi office handles Vietnamese.
What Happens If You Ignore This
If you try to operate in Indonesia, Vietnam, or Thailand with only English and no local language support, one of three things happens.
First, you get stuck at the surface level. You can have meetings, but you cannot execute. Deals stall because contracts cannot be finalised. Problems do not get resolved because you cannot communicate with the people who actually handle operations.
Second, you become completely dependent on intermediaries. Every conversation goes through a translator or a partner. You have no direct visibility into what is actually happening. If your partner is lying to you or underperforming, you will not know until it is too late.
Third, you miss opportunities. Potential customers, partners, or employees who do not speak English never even enter your radar. You are fishing in a tiny pool when the ocean is right there.
The Bottom Line
You do not need to speak Indonesian, Malay, or Vietnamese to do business in Southeast Asia. But your operation needs that capability.
If you are selling to large multinationals or operating only in Singapore and the Philippines, English is enough. If you are going into Indonesia, Vietnam, Thailand, or working with Malaysian SMEs, you need local language support.
The most practical solution is to hire local staff who are bilingual, or partner with local distributors who can handle the language side whilst you manage strategy. Trying to operate without local language capability is possible, but it is slow, expensive, and risky.
