This could get interesting. Not that they need my advise, but I’d advise the Vietnamese to prepare for border incursions and/or cross border artillery fire.
Is this China testing the US? Seems to me they did so when they went into Vietnams territorial waters to drill?
Appears China’s on the move now without much concern for how the US Administration would respond.
However, we fought Vietnam and we all know how that turned out....of course the Chinese will fight to win if it comes to that.
