The Vietnamese, concerned about China's growing navy and amidst tensions over the Spratley and Paracel archipelego, have agreed with the Russians (I think this is the best link for info I have found, despite the "Kilo" class submarine misidentified in their photos) to buy 6 Kilo class subs and some aircraft.
What does this mean for us?
As we cultivate our relationship with the Indians, and affirm it with the Japanese, we need to also be looking at other regional powers to counter the Chinese.
Hopefully, the Obama administration has some adults in the State and Defense departments who can see past the fact that China is bankrolling the American Left's Spending Spree, and we will act with something other than complete deference and kow-towing to the Chinese.
We shall see.
