US President Donald Trump is the deadline of March 1
Chinese and US officials will hold high-level statements this week aiming to stop their destructive trading war.
US officials have previously said March 1 is a deadline for a deal to avoid additional tariffs.
Both countries have imposed duties on billions of dollars worth of goods one by one.
City-level statements began this week in Beijing. High-level discussions, led by Secretary of the US Secretary of Steven Mnuchin and Chinese Premier Premier Liu He, will begin on Thursday as both sides are rushing to make progress before the March 1 deadline. "If we are close to a deal where we think we can make a real deal and it's done done, I can see myself letting that slide for a little while," Mr Trump said refers to the March 1 deadline.
"But in general, I'm not inclined to do that."
The US imposes tariffs on $ 250bn (£ 193bn) worth of Chinese goods, and China reacts by imposing duties on US $ 110bn of US products.
In December, both countries agreed to stop new tariffs for 90 days to allow the talks.
The US said it would raise tariff rates to $ 200bn of Chinese import value from 10% to 25% if the two sides did not hold the deal by March 1.
Surprised Mr. Trump also adds additional tariffs to an additional $ 267bn worth of Chinese products.
Washington forces Beijing to make changes to its economic policies, which claim to be unjust in favor of domestic companies through subsidies and other support. ] It has also accused the government of supporting technology theft as part of its broader development strategy, while in China there is a sense that the US uses the war to expand the country's rise.
