With the rise in China economy and its influence on the rest of the world, how can Singapore navigate to benefits its economy without jeopardizing its close relationship with the US and Europe?

There's no point worrying about that since Singaporeans dont have much say and sway over Singapore's foreign diplomacy.

However, I am pretty sure if the chips are down, Singapore will prefer to do business with partners that value and honor contracts and dont treat them as historical documents once the dust is settled.
