When a Chinese submarine entered the Malacca Strait on December 20, heading towards the Indian Ocean, there was speculation about where it was going. This was answered when it pulled into the Yangon River, Myanmar, on December 23. Literally the next day it was commissioned into the Myanmar Navy as UMS Minye Kyaw Htin.

The sale, or transfer, had not been announced in advance. It highlights the growing influence of China in the region and the role submarine sales play in the geopolitical arena.

And China’s impact on the world submarine market. China is now supplying 4 countries with submarines. More may follow.

Submarine Diplomacy

Buying submarines is not like cars, where you select a model, and pick from a catalogue of features. They are not bought off the shelf, instead each aspect has to be defined. The location where they are to be built, the degree of customization, crew training, and ongoing maintenance are all part of a typical deal. And there is always a geopolitical aspect, and often government-to-government negotiations.

And it is not simply commercial. Governments can supply submarines to help create, or reinforce, alliances. Or at least expect favorable future relations going forward. This is especially true if the submarines are provided free, or at a major discount. One way to do this is by supplying older submarines from their own inventory. It can be a win-win and limits the risk if politics change in the future.

The Chinese submarine for Myanmar is more complex than most in a few ways. Although China has been Myanmar’s main defense supplier for many years, it had not been in the frame for submarines. Instead, India and Russia had. Externally, it might be seen as a stab in the back to Indian efforts.

Myanmar has been trying to establish a submarine capability for about two decades. Exactly a year earlier on December 24 2020 the Myanmar Navy commissioned its first submarine, the UMS Min Ye Theinkhathu. Significantly, that submarine had been transferred by India, China’s immediate rival in the Indian Ocean region.

Both submarines are relatively old types, and both are second-hand. The Chinese one is a Type-035 Ming Class, and the Indian one is a Russian-built KILO class boat. Despite arriving second, the Chinese boat is hardly an upgrade over the Indian supplied one. In fact, the KILO is generally considered the more capable platform, although the exact details of their equipment fit are naturally harder to pin down.

So the sudden acquisition of an older Chinese boat is not about modernizing Myanmar’s capabilities. It is instead part of a bigger picture. China is presumably expecting to bag the follow-on order or more modern boats. And solidify its geopolitical position in the Bay of Bengal in the process.


China has done something very similar in the past. In 2017 it supplied two ex-PLAN (Chinese Navy) Type-035 Ming Class submarines to Bangladesh.

Market Warfare

For the past few decades, the submarine export market has been dominated by France and Germany. These big players are already being challenged. These include new entrants South Korea, Spain and Japan, and reemerging established players like Sweden. And of course Russia has a stake in submarine exports. Now China is joining the club and rapidly rising towards the top.

China is already supplying four nations with a total of 12 submarines. The largest, and likely most sophisticated, deal is for Pakistan. The Pakistan Navy is getting eight Type-039B Yuan Class submarines, with four being built locally. These missile-capable submarines come with AIP (Air Independent Power).

Thailand is getting another Yuan, designated S26T. Meanwhile ex-PLAN Type-035 Min Class boats, which are less capable than the Yuans, have been supplied to Bangladesh (2) and now Myanmar (1). China is known to be courting other countries with submarines, notably Nigeria.
