The Chinese response was positive but more tempered.
When talking about China's reform and opening-up, Xi said a comprehensive and systematic overhaul of both Party and state institutions has been unveiled, adding that over 100 major reform measures were launched in the country.
China and the U.S. have been locked in a trade war for much of 2018, shaking world financial markets as the flow of hundreds of billions of dollars worth of goods between the world's two largest economies has been disrupted by tariffs. As NPR's Rob Schmitz reported, US tariffs on $200 billion worth of Chinese imports, which were scheduled to increase to 25 percent on January 1 have remained at 10 percent as a result of that temporary truce.
The US has hit $250bn of Chinese goods with tariffs since July, and China retaliated by imposing duties on $110bn of US products.
In his message to Trump, Xi said China-US relations had experienced ups and downs but made historic progress over the past four decades, state news agency Xinhua reported.
Chinese Foreign Ministry spokesman Lu Kang further stated China "stands ready to work with the U.S." on an agreement, expand co-operation in a mutually beneficial way and "manage differences on the basis of mutual respect".
The Chinese leader expressed a wish to develop trade, economic, military, law enforcement and anti-drug cooperation with the United States next year that will mark the 40th anniversary of the establishment of the bilateral relations.
Trump took to twitter on Sunday saying he had a "long and very good call" Xi and that trade deals were in progress.

Besides worries over the hard U.S.
Unusually, it was Mr Trump who first confirmed his call with Mr Xi, not the other way around.
Ending his speech, Xi reaffirmed that China's honest commitment to safeguarding world peace and promoting common development will remain unchanged. -China trade talks, much of current angst is focused on the Federal Reserve, which faces a tricky balancing act of boosting interest rates enough to contain inflation without choking off the economic expansion.
