The company's goal is to be the main destination for connecting international retailers with Chinese consumers.
Alibaba plans to create the new jobs by adding 1 million small and medium-sized US businesses and farmers to Alibaba's platforms, estimating that each one will hire a new person as a result of the added commerce.
Higher tariffs, were Trump to follow through with campaign rhetoric, would depress demand for the AliExpress site, where Chinese retailers sell to US consumers. Any ensuing trade disputes could hurt sales on Alibaba's Tmall platform, through which US and international brands sell to Chinese consumers.
That would set back Ma's goal to derive about half of the company's revenue from outside China to offset any slowdowns at home.
Last year, 7,000 US brands on Alibaba's platforms made sales worth $15 billion to Chinese consumers, according to the company. After the 40-minute meeting, the company tweeted it "wants to create US jobs by helping US small businesses and farmers sell to China's 300 million-strong middle class."
US produce sold on Alibaba's platforms include Pacific Northwest cherries, Washington State apples, and Alaskan seafood.
Alibaba shares rose 0.9 per cent to $94.74 at 2:37 p.m. in New York.
Trump's meeting with Ma comes just a few weeks after he met with SoftBank Group chief executive officer Masayoshi Son. In that meeting, Trump took credit for a previously announced investment by SoftBank and 50,000 jobs that fund would help create in the US.
Several other companies -- from IBM to Ford -- have also unveiled plans to create jobs in the country since Trump's election, though some of the plans had been in the works before the election was decided.
