In recent months, the American effort has begun to show results.

Yet the reasons and the goal of the American effort remain unclear.

China has long worried about American efforts to "contain" its power, both military and economic.

But many specialists say there will have to be more of an American effort than one visit.

The techniques were two years more advanced than American efforts.

But the American effort appeared to be weeks too late.

Instead, it gave about $13 billion in financial assistance to that American effort.

And what do they hope to achieve in view of the American efforts?

Because they've always wanted this to be an American effort.

So the American effort to strike a balance is delicate at best.
