China's slowdown is becoming a real headache for US semiconductors, prompting them to warn investors about soft sales in the country.

On Monday, the chipmaker Nvidia slashed its fourth-quarter sales guidance, citing significantly weaker economic conditions in China and disappointing sales of its gaming and datacenter platforms.

Nvidia follows Intel, Texas Instruments, Lam Research, and TE Connectivity in blame slumping sales on a slowdown in China.

During the fourth quarter, China's economy grew at a 6.8% year-over-year clip, its weakest pace in at least a decade. And in December, China's private-manufacturing sector contracted for the first time in 19 months as industrial profits posted their second consecutive monthly drop.

President Donald Trump's trade war has added uncertainty for companies seeking to do business in the US and China. So far, the US has imposed tariffs on $250 billion Chinese goods, promoting China to retaliate on a smaller scale. Trump, in September, threatened to impose tariffs on another $267 billion worth of Chinese imports, but later agreed to delay them until at least the end of February. The two sides will hold meetings on Wednesday and Thursday in Washington as part of their latest round of trade talks.

The semiconductor industry, which relies heavily on the manufacturing steps in multiple geographic regions, needs the world's two largest economies to maintain a good relationship, William Stein, an analyst at Sunset Robinson Humphrey said in December.
