There's a couple of regulations for selling GPS enabled devices in China (I am a software guy on a major PND manufacturer with products being sold in China).

- The map data is scrambled (GPS coordinates are encrypted). - To correlate a GPS position with the map data, you plug the HW position through an encryption library (which you have to compile in a specific government building in Beijing). - Border drawing is strongly regulated: no border line between Mainland China and Taiwan, Tibet is of course China, South East Asia Islands can't have border lines drawn and Kashmir is a big thing also with border lines. - You can't show pure GPS coordinates - You can't include a number or POIs in your map (mostly government buildings/facilities).

As a note, India as a certain degree of insanity as well: You can't export a map. Launching a PND there involved shipping a bunch of map technicians there to actually make sure we never got a map outside of India...

so what you're calling scrambling/encryption is actually a transformation? the encryption library transforms the coordinates so that they match the distorted map?

what is the advantage of this? couldn't an attacker get a copy of the software? is there some kind of real-time authorisation step so that they can disable the transformation or change it?

[edit: thanks; wasn't thinking you thought it a good idea, just curious for more info]

[machinagod]

Yes... it's not very hard to reverse engineer.

I'm not questioning the advantage (in my view it's a small roadblock if you're motivated enough to actually get the data) just stating an inane regulation...

Everywhere in China you can buy illlegally imported smartphones (cheaper, avoids chinese sales taxes) from Hongkong, all with GPS included.

One country, two systems.

This makes me wonder if I brought my US Android phone to China to use it as a Wifi tablet device, am I technically breaking the law?

> Tibet is of course China

Do you guys put Tibet as disputed area on like 90% of the maps in the West? Really?

[tokenadult]

On most maps published in the West, Tibet is shown as an integral part of the territory of the People's Republic of China, even though plenty of Americans drive around with "Free Tibet" bumper stickers on their cars. That is the GOVERNMENTAL position of the United States at present, that Tibet is part of the territory of China. (Of course historical Tibet includes regions outside the current boundaries of the Tibet Autonomous Region administrative division of China, including most of the territory of what is called Qinghai Province and quite a bit of land in Sichuan Province.)

The case of Taiwan is even more confusing. A world globe I have from a decade ago, commercially published by a private business corporation rather than officially published, shows Taiwan and the mainland territories of China in the same color. (Usually this globe distinguishes different countries by different colors.) However, the globe also marks the location of both Beijing and Taipei (so spelled) with a star symbol indicating a capital city, suggesting that Taipei is the seat of a national government. United States law under the Taiwan Relations Act strikes a delicate balance between agreeing with the original assertion of both the P.R.C. and R.O.C. regimes that there is one China and Taiwan is a part of China and the current facts on the ground that China (the P.R.C.) and Taiwan (the island of Taiwan and various outlying islands, including some that historically were part of Fujian Province) are under distinct national administrations.

The Wikipedia article on Taiwan independence

http://en.wikipedia.org/wiki/Taiwan_independence

seems to have enjoyed some good editing back-and-forth so that it is not entirely slanted to one point of view or another.

[mrtron]

Here is my perspective on Taiwan grossly simplified.

A bunch of Han Chinese moved to the island. The Dutch established a small colony there. Japan took over. Post-WW2 they were given independence from Japan. The pre-communist leader of China moved to Taiwan and took over politically. The KMT party ruled until recently, when Taiwan peacefully transitioned to a democracy and now has two main parties.

There is nothing in Taiwan under Chinese control. They have their own government, constitution, military, their own passports that are recognized worldwide, etc. However, there is a looming threat that China will attempt to take over which drives mandatory military service, and tight relations with the US.

[blasdel]

You don't understand the problem at all.

Both PRC and ROC say that Taiwan is entirely under Chinese control, that there's only one China, and that they govern all of its territory.

[marshray]

But it's an interesting question how much of that is really a facade and how much it's relevant.

Obviously, Taiwan has no plans to reconquer the mainland any time soon. However, PRC China threatens that if Taiwan formally declares independence it's back to a shooting war.

So yes, Taiwan still maintains governors for the areas of the mainland (last I heard they're all very old as they obviously are not standing for reelection back in their home district). This surprises people when they first learn of it.

It seems to a lot of outsiders like it is more about preserving the very carefully kept status quo than it is about a serious territorial claim.

But I don't really know that much about it. This topic tends to bring out strong opinions in people on one side or the other and I haven't come across many people who do know both sides who will chat freely.

[mrtron]

That is oversimplified to the point of inaccuracy.

Taiwan is a democracy, and one of the major parties firmly opposes any concept of Chinese rule and seeks recognition of Taiwan. The other party leans towards being the sole leader of all of China. However in practice (being currently elected) they just improve economic ties with China while opposing unification or formal recognition of Taiwan.

The PRC sees Taiwan as a province of China that they should rule, as you mentioned.

> The PRC sees Taiwan as a province of China

FYI the ROC also sees Taiwan as a province of China. There is another province called FuJian province, ROC.

It is also worth noting, and easily forgotten, that part of 'historical' Tibet is in India.

Already been one war fought along that border.

[est]

> that part of 'historical' Tibet is in India.

It's also worth noticing that India was never an integral country in the past.

[danbmil99]

It's also worth noting that Human Beings are territorial animals, and there are hundreds if not thousands of disputes like this all over the world. Cypress and Kashmir come to mind, but there are plenty more.

Really? Citations?

What this reminds me of is USA's inane attempt to control encryption technology. Every state is used to controlling information, the tech is just moving too quickly for bureaucracies to even respond.

I'm sure there are thousands of Chinese engineers with careers transforming map coordinates. You don't want to put these people out of a job, do you?

Humans are funny.
