What is the current account for each country?
Vanyuwa [196]

Answer:

The country that has a trade deficit  is US and the country that has a trade surplus is China.

A country has a trade surplus if the value of export is greater than the value of import.

A country has a trade deficit if the value of export is less than the value of import.

If the US buys goods from China, it is considered import to US and export to China

Total value of export in China / Total value of import to US:

Cost of goods and services purchased + humanitarian aid + amount spent by tourists + amount spent in the stock market

$800 + $100 + $200 + $1000 = $2100

Total value of export in US / Total value of import to China:

Cost of goods and services purchased + humanitarian aid + amount spent by tourists  

$1000 + $300 + $600 = $1900
