In-depth: Global market wrap-up

Time now for an in-depth look at the market news.
And for that, I'm joined on the line by Dr. Yang Jun-sok, professor of economics at the Catholic University of Korea.
Dr. Yang, thank you as always for coming on.
The Catholic University of Korea} Thank you.
Some less than positive news for those hoping for a trade deal between the U.S. and China. President Trump warning China that if there is no deal, he'll raise tariffs even higher. What's the story in the markets today?
The IMF is saying that even if the U.S. and China do strike a deal, economies like Korea, the EU and Japan will be affected. Why is it that their exports would be hit and how badly would Korea be affected?
Moody's is keeping its sovereign credit rating for Korea at double-A, but it's pointed out some weakness in Korean companies. Of the 24 it monitors, it has a negative outlook for 14 of them. What do you make of the situation?
Alright Dr. Yang. We'll have to leave it there for today.
Thanks for sharing your insights, as always.
