Update: Recent versions of this no longer include the list of top-level domains (.aisa, etc.), presumably because a fair number of people who might have actually been concerned about the issue simply went off to their favourite registrar and registered the names. Or maybe it's just that the more vaguely worded message inspires a better response rate. Either way, it's the same scam.

If you get a mail message from a company purporting to be located somewhere in Asia that looks like this:

We are the (some group usually referring to domain registrations and disputes), we have something we need to confirm with you. We formally received an application on (recent date). A company called "(random registering company name)" are applying to register "(your brand)" as Brand Name and Domains.

(your brand).asia (Asia)
(your brand).cn (China)
(your brand).com.cn (China)
(your brand).com.hk (Hong Kong)
(your brand).com.tw (Taiwan)
(your brand).hk (Hong Kong)
(your brand).in (India)
(your brand).net.cn (China)
(your brand).org.cn (China)
(your brand).tw (Taiwan)

But we found that "(random registering company name)" is not the original owner of the brand and trademark in the checking period, which belong to your company. I need confirm with you whether your company authorized that company to register these domain names. If you have done that, we will finish the registration for them and link to their website. If not, please let me know ASAP.

Then ignore it. It's a scam. Eventually they'll offer to register these domains for you for a ludicrous fee ($2000 for domains that should cost a few hundred dollars at most). You can also expect that they'll actually retain ownership of the domains if you're gullible enough to proceed, so they can really hold you hostage in another year.

The anti-spam tool site firetrust.com has a good description of the issue that features several posts of domain scam spam mail in the comments.
