Hey, I’m Kojo (the voice behind Explore With Kojo). As someone who comes from Africa and has explored dozens of countries around the world, I’ve always been fascinated by Southeast Asia. It’s a region full of contrasts indeed. And over time, I’ve come to appreciate how much growth and transformation has happened here in just the last few decades.

I personally think that development isn’t just about GDP or skyscrapers. When we talk about development we are also talking about infrastructure, education, healthcare, digital connectivity, governance, and quality of life. Some countries in Southeast Asia have managed to rise above the rest in these areas, setting an example for others to follow.

Here are the Top 10 Most Developed Countries in Southeast Asia, based on what I’ve seen, experienced, and researched.

1. Singapore

There’s no contest Singapore is hands-down the most developed country in Southeast Asia. I’ve visited several times, and each time I’m amazed by how advanced it is. The MRT system (rapid transit system) is fast, safe, and extremely clean. You can drink water straight from the tap in this country without needing to filter it because the water is very, very clean. Public spaces are clean, efficient, and thoughtfully designed. And the airport? Don’t even get me started on Singapore’s Changi airport. Believe me when I say it’s a destination on its own.

Singapore ranks among the top countries globally for education, governance, digital innovation, and healthcare. It’s also one of the safest places I’ve ever been. What’s even more impressive is that this was all built without natural resources. They used vision, good leadership, and relentless planning to build the miracle that Singapore is today. Honestly no country in the world has impressed me the way Singapore has success-wise.

It should be noted that in addition to being the most developed place in the whole of Southeast Asia, Singapore is also the safest city in that region.

“Singapore didn’t rise by accident. It rose by design and it shows in every detail of daily life.”

2. Malaysia

Malaysia has made remarkable strides in development, especially in fast-growing cities like Kuala Lumpur, Penang, and Johor Bahru. The first time I stepped foot in KL, I was genuinely impressed. I wasn’t just amazed by the iconic Petronas Towers lighting up the skyline, but by how organized and connected the city felt. The highways are smooth, the infrastructure is solid, and there’s a real sense of energy in the air.

What really stood out to me, though, was how Malaysia is managing to grow without losing its identity. You’ll find gleaming malls and high-speed internet, but just a short drive away, there are traditional kampungs and historic sites that are still very much alive and respected.

The country’s growing digital economy, decent public transportation networks, strong healthcare system, and a multilingual, diverse workforce all play a role in pushing Malaysia forward. No, it’s not quite at Singapore’s level yet but it’s definitely one of the most developed and promising countries in Southeast Asia, and it’s only getting better

3. Thailand

Thailand is way more than street food, temples, and those picture-perfect islands. That said, please don’t get me wrong, those things are amazing too. What surprised me the most was how modern and convenient life can be, especially in cities like Bangkok. The city runs on skytrains, high-speed internet, and QR codes. And you can pay for almost anything with just your phone.

Walk through Bangkok and you’ll see luxury malls sitting side by side with centuries-old shrines. The hospitals are also world-class. It’s no wonder Thailand is one of the top destinations in the world for medical tourism. People fly in from all over just to get treatments that are both affordable and high quality.

Of course, rural areas in the country still face challenges relating to slower development and less infrastructure but the country as a whole is pushing ahead.

4. Brunei

Brunei may be small, but it’s wealthy and highly developed. This country was able to see massive development thanks mainly to oil and gas revenue. Today Brunei has excellent public services, free healthcare and education, and a relatively high standard of living.

The capital, Bandar Seri Begawan, is well organized and clean. You won’t see chaotic traffic or pollution here. One thing about Brunei is that it doesn’t chase growth for the sake of it. The country actually invests in quality, and you will see it wherever you go.

5. Vietnam

Vietnam has transformed rapidly over the past two decades. Cities like Hanoi, Da Nang, and Ho Chi Minh City are growing fast, with modern transport, reliable internet, and a thriving startup scene.

Infrastructure projects like new metro systems and expressways are changing how people live and work. What struck me was the energy in the country. Vietnam feels hungry, focused, and determined to rise. It’s already one of the fastest-growing economies in Asia.

6. Indonesia

Indonesia is Southeast Asia’s largest economy and a rising power. Jakarta, despite its traffic woes, is a mega city with malls, highways, and growing tech hubs. Bali, on the other hand, is a case study in digital nomad comfort with co-working spaces and smart cafes everywhere. Being a digital nomad myself, I was totally impressed by this.

That said, Indonesia has challenges ranging from inequality to infrastructure gaps to environmental concerns. But its growth trajectory is undeniable. The new capital being built in Kalimantan shows just how ambitious the country is.

7. Philippines

Manila can feel chaotic, but underneath the surface, the Philippines is advancing in key areas, especially in digital services, healthcare, and outsourcing. Filipinos are also one of the most connected populations in Southeast Asia, with high social media usage and tech adaptability.

The country faces challenges like congestion and income inequality, but places like Cebu, Davao, and BGC (Bonifacio Global City) give a glimpse into the Philippines’ modern side.

8. Cambodia

Cambodia is still developing, but it’s making real progress. Phnom Penh is growing fast, and tourism infrastructure in Siem Reap is world-class. Roads, schools, and healthcare access have all improved in the last decade.

What stands out is how quickly Cambodia is catching up, especially when it comes to foreign investment and regional cooperation. It’s not quite there yet, but the foundations are being laid.

9. Laos

Laos is one of the least developed countries in Southeast Asia, but it’s starting to change. The new high-speed rail line connecting China to Vientiane is a big deal since it’s opening up access and trade like never before.

While rural areas are still underserved, infrastructure is improving fast. Laos remains largely agricultural, but it’s slowly stepping into a new era of development.

10. Myanmar (Pre-Crisis)

Before its recent political instability, Myanmar was on a fast track to development. Yangon was growing, foreign investments were pouring in, and tourism was booming. I visited before things escalated and saw clear signs of potential such as new roads, rising tech hubs, and expanding education initiatives. Unfortunately, conflict has disrupted that growth. But I believe that with peace and good leadership, Myanmar has the talent and resources to develop rapidly in the future.
