I found a top 10 list of the most expensive cities in the world from AOL website. I wonder what is KL world ranking at the moment. 

1. Moscow. Cost of living index = 134.4
With over 50 billionaires rumoured to be living in Moscow, it's no wonder the trickle down effect has started to flow. The cost of a coffee is £3.14."The appreciation of the Rouble against the US Dollar, combined with ever-increasing accommodation charges, has driven up costs for expatriates in Moscow," said Yvonne Traber, research manager and senior associate at Mercer.

2. London. Cost of living index = 126.3
We've all heard the tabloid chant of 'Rip-off Britain!'. Well spare a thought for Londoners, who bear the brunt. With average property prices hovering at £350,000, that's around 10-12 times the average rate of income."Steep property rental costs, together with the strengthening of the British Pound compared to the US Dollar, have contributed to the city's high ranking," commented Yvonne Traber.

3. Seoul. Cost of living index = 122.4
With just a 3.4% unemployment rate, and the strength of the Won against the Yankee dollar, Seoul is flying high compared to New York standards.

4. Tokyo. Cost of living index = 122.1
A two-bedroom unfurnished apartment in Tokyo costs around £2,110 to rent per month, proving that the land of the rising sun is also a place of rising costs.

5. Hong Kong. Cost of living index = 119.4
Hong Kong may be the destination for affordable electronic goods, but high property prices keep the former British colony high on the list.

6. Copenhagen. Cost of living index = 110.2
Heralded for its high standards of living and atmosphere of social equality. But a burger costs £4.99...

7. Geneva. Cost of living index = 109.8
Perhaps known for its private - ahem - 'offshore' banking services, Geneva holds some estimated £500billion, which goes to prove that money simply attracts more money. Some items in Geneva shops are thought to be as much as 10% more expensive than in Zurich.

8. Osaka. Cost of living index = 108.4.
Once Japan's major economic centre, Osaka is still an expensive place to live, which makes the seemingly low average income per head (£13,318) a mind boggle.

9. Zurich. Cost of living index = 107.6
Fortunately for its inhabitants, some of the highest wages in Europe are paid in Zurich.

1o. Oslo. Cost of living index = 105.8
Based on a cost-of-living score for New York set at 100, prices in Norway's capital are a little ripe compared to the Big Apple.
