A few other unexpected trends in the region,Interesting triangle.
Hun Sen was installed by the Vietnamese and is still regarded as their puppet by opposition parties in Cambodia.
The Vietnamese hate the Chinese especially over the Spratleys etc.
The Chinese have been pouring money into Cambodia recently, with a large amount into Hun Sen's pocket.
He's definitely Hanoi's man but likes the feel of a wedge in his pocket...
Although the Vietnamese dislike the Chinese, trade and tourism between the two countries is increasing at a fair clip.
The other trend, less publicised is that the Americans are becoming quite friendly with the Vietnamese, to the extent that some military airplanes land and re-fuel at Da Nang whilst in transit. Hitherto to a certain point this was happening at Phnom Penh Pochentong airport in Cambodia, but relations between the Americans and Cambodians have become chillier recently.
Should Chinese military facilities ever be established in the Gulf of Siam, the Thai government may feel they need to have a US presence again at their former base of U-Tapao.
May we live in interesting times............
