I strongly believe China's 2020 GDP will be above ¥103 trillion RMB. Given the exchange rate of currently of ¥6.46 = $1 USD, that equates to China's nominal GDP in dollar terms equivalent to $16 trillion USD for 2020, almost 80% of the US GDP!
Not really, last year's GDP will be converted to USD using the average yuan/dollar exchange rate of last year, which is about 6.89. So the $GDP will be just udner $15 trillion. But this year's $GDP will get a huge bump from the appreciation of the yuan in the latter part of last year, assuming the same exchange trend and GDP growth rate of 8-9%, as most economists expect.
