Hello, I'm Tian Wei.

I'm standing here in the city of Hanoi. Behind me is the wreckage from the American planes from the Vietnam War in the 1970s.

That war left millions dead, and its influence is still being felt here in the city loud and clear. Wreckage, like this, you can find almost in every corner of the streets and downtown. Despite their checkered history, Washington and Hanoi are getting ever closer geopolitically. And as a result of that, the city of Hanoi has also become the host city for the second Kim Jong Un-Donald Trump Summit.

Signs calling for peace between Washington and Pyongyang can be seen everywhere in the city of Hanoi, including certainly here at the International Press Center for the summit. Look at that, the flags made of roses, fascinating and beautiful. And yet, the question is, after that, what is next? And is whether the two countries are ever coming closer for peace? What is going to go down in history? And how?

If you look at Pyongyang and Washington, the most basic relations have yet to be achieved. The two are still technically at war－the Korean War. No peace mechanism has yet been established since American troops withdrew from the Korean Peninsula decades ago. So far, as everyone in the world knows, the real discussions about the peace mechanism almost do not exist, and the involvement of other direct parties in that war about a peace mechanism is even less.

Secondly, the DPRK has become a nuclear state. It is using its nuclear capability as a strong security guarantee and a bargaining tool against the U.S. and its allies. In other words, it could hardly denuclearize unless it's guaranteed to be secure and to live in a way that it considers dignified.

Well, if you look at its logic, getting along in peace should not be very difficult to achieve.

But it was extreme tension rather than anything else not long ago, until the very first Kim-Trump Summit in Singapore. Lights, cameras, and action! What a show! But the question is how much of the actions under the spotlight are really leading to real actions for the denuclearization of the Korean Peninsula?

Given the history of distrust and ill feelings toward each other, no wonder many scholars believe that－with Washington and Pyongyang－neither side should be expected to do anything before the other side does anything. Well, hard to get? Well, again: neither side should be expected to do anything before the other side does anything.

So now the question is what would lead both sides to do anything toward the right direction as soon as possible? And eventually, everything?

The reality show-style summit has to be replaced by the real detailed and hard work, which would bring about a mutually-accepted step-by-step plan. And that plan has to clearly mark both the sequence and the real actions that both sides have to follow for the DPRK to embark on a journey toward denuclearization. Not just to stop provocations, but real steps to denuclearize.

For the U.S., as a beginning, to work technically toward the end of the Korean War and provide a security guarantee and economic opportunities that Pyongyang considers as the bottom line.

That is what the second round of the Kim-Trump Summit really has to achieve.

But, that would not happen easily. Neither side has credibility in the other's eyes. Meanwhile, other stakeholders that should be directly involved in establishing a peace mechanism are not included in this summit.

But for now, let's try to embrace what we have as much as we can. When the second Kim-Trump Summit takes place, let's wish it well. Let's be comforted by the fact that, at least, the two sides are apparently walking toward each other, though possibly only small steps at a time.
