Which country is the most corrupted in Asia-Pacific?

There are two ranking of corruption perception in Asia-Pacific, I am familiar with: That of Transparency International (TI) from Germany , and that of Political & Economic Risk Consultancy (PERC) from Hong Kong .

Most corrupted key nations in Asia Pacific

3	Vietnam	Vietnam
4	Philippines	Indonesia
5	Thailand	India , Thailand
6	India	-
7	China	China
8	Malaysia	Malaysia
9	Taiwan	Macau

11	Macau	Taiwan
12	Japan	United States
13	United States	Japan
14	Hong Kong	Hong Kong
15	Australia	Australia
16	Singapore	Singapore

It seems that the biggest gap between these two ranking, is about the position on Indonesia . I would recommend the Indonesian government to contact these two ranking bodies, - and understand where the difference come from.

I suspect, the difference is coming from a gap between the perception of local and foreign businessmen about corruption.

If Indonesian government want to attract foreign investments here, - it should do whatever it can to convince the foreign investors that Indonesia is less corrupted.
Of course, the best way to do so, - is by really fighting corruption. A fight against corruption should include a deterrent war against those personalities and entities that are sabotaging the war against corruption. The current government is too weak to do so, and other entities, like some corrupted and populist parties are taking advantage of this weakness by fighting the enlightened figures in the government.

This is how the HK based organization defined the Century Bank drama: "The Hong Kong-based consultancy said Indonesian lawmakers' call for a criminal probe into the Yodhoyono government's bailout of Bank Century in 2008 reflected attempts by a corrupt establishment to maintain the status quo."[source]

By the way, according to PERC, Indonesia is perceived as more corrupted in 2009 than in 2008. Its grade for 2008 was: 8.32, while in 2009 it got: 9.27 out of the worst possible 10. Other numbers for 2009 are: Singapore : 1.42, Malaysia : 6.47, China : 6.52, India : 7.18, Thailand : 7.60, Philippines : 8.06, Vietnam : 8.07, and Cambodia : 9.27. A real shame for Indonesia .
