While neither of these two energy products were mentioned by name, it's likely that China would not only appease the U.S.by removing tariffs on U.S. LNG imports but would also help itself since Beijing needs the diversity of supply that growing U.S. shale oil and gas exports offer.
Chinese purchases for the aforementioned products have almost completely halted after Beijing imposed tariffs on them in response to the US tariffs on Chinese goods.
That's more detail than was in a Wednesday statement from China's commerce ministry that said the trade meeting with the US was "very successful" and expressed confidence in implementing the agreement - but didn't provide any further details on the outcome. China's crude oil imports from the USA had ground to a halt.
In return, China agreed to buy what the White House called a "not yet agreed upon, but very substantial" amount of USA products to help narrow America's gaping trade deficit with China.
"If it is, we will get it done", Mr Trump said in a Twitter post.
The move is an extension of a dinner the two had at the G20 summit, where they agreed to not increase tariffs for 90 days in order to pave the way for discussions. It wasn't clear whether the preparations meant China would cut the retaliatory tariffs it imposed on those products, or when the purchases would happen.
The two leaders on Saturday agreed to the ceasefire in a trade war that has seen the flow of hundreds of billions of dollars worth of goods between the world's two largest economies disrupted by tariffs.
One of the agreements signed were of China to remove auto tariff.
A vow by China to reach a trade settlement with the United States has helped settle financial markets after steep falls in U.S. stocks.
The Ministry said that the recent meeting of U.S. President Donald trump and Chinese President XI Jinping was successful.
"Narrow agreements and modest concessions in the ongoing trade dispute will not bridge the wide gulf in their respective economic, political and strategic interests", Moody's Investors Service said in a report that predicted U.S.
The United States also expects China to promptly address structural issues, including intellectual property theft and forced technology transfers. China's government has yet to issue official comment on those details.
Mr Xi and his most senior officials, including the Commerce Minister and the country's two top diplomats, are in Portugal, and due back in China on Thursday.
