This had received immediate attention of researchers worldwide due to the involvement of vast economies in this. This paper reviews the studies conducted in recent past i.e. last two years 2018-2019 and explored the reasons behind initiation of this war, its impact on US, China and world economy. It is concluded after review that none of the economy is benefitted due to these conflicts, rather there is decrease in trade and GDP of US, China and world economy.
