The inauguration of the tallest building on Earth - the newly re-named Burj Khalifa in Dubai – in the midst of almost worldwide instability in property prices – could seem like flying in the face of logic.

At the opening ceremony, which revealed the building's 2,700 foot height for the first time, the developers tried to put a brave face on things. But in the midst of Dubai's financial and property crisis, values of many of the luxury apartments have dropped by 50% or more.

Many proud Chinese net users were a little upset at the desert skyscraper's record-breaking height – the next three names on the tallest buildings list after all are the Taipei 101 tower, the Shanghai World Financial Center and the Hong Kong International Commerce Center.

But with the property crash and Dubai's financial troubles the tone of those comments has changed. Our researcher Jackie Wen has been following the chat online and joins us now from the news room.
