The trade war between the world's two largest economies has threatened to disrupt the global economy. Both sides agreed not to levy any new tariffs against each other's products for now.
"For the time being, we'll like to cease investment to China. So, truce means postponement," Niinami said.
Although Suntory is still operating in China, Niinami said the company needs further clarity on the U.S.-China trade dispute before further investment decisions can be made.
"I wonder if we should promote producing products in China or still keep production in Japan and export products to China," Niinami said.
Such concerns are a reflection of what businesses are thinking about amid the U.S. and China tariff fight, causing a domino effect of disruptions in the supply chain.
So, Suntory is staying put in Southeast Asia where it has operations in Vietnam, Thailand and Indonesia. The emerging regions are also home to a large, young population of potential consumers.
Niinami is also bullish on India, where the most whisky in the world is consumed.
Although India's spending per capita on whisky is not as high as that in developed markets, the South Asian country has "huge potential," he added.
Suntory is adapting and shifting strategies as it grapples with changing alcohol consumption patterns, such as the fact that millennials are generally drinking less.
In the U.S., sales growth across various alcohol types are slowing, data from global market research firm Nielsen shows.
To help sell alcohol to millennials, Suntory is marketing more premium alcohol types. It is also trying to attract beer drinkers to consume more premium products.
"Beer carries a lot of calories," Niinami added.
The Japanese company has captured the attention of whisky connoisseurs in recent years.
In addition, Suntory talked about alternative ways of drinking whisky and premium spirits, such as mixing them with carbonated water. The strategy has been popular in the U.S., and appeals to younger female drinkers as well, he added.
"We are not selling bottles, we are selling freshness of our products," said Niinami.
