(Updates with Russian oil tariffs, Madrid talks)

By Liz Lee and Shi Bu

BEIJING, Sept 16 (Reuters) - U.S. President Donald Trump

has targeted top economic rival China with a cascade of tariff

orders on billions of dollars of imported goods aimed at

narrowing a wide trade deficit, bringing back lost manufacturing

and crippling the fentanyl trade.

The timeline below shows the development of the U.S.-China

trade war this year:

January 21 - A day after taking office, Trump threatens 10%

punitive duty on Chinese imports, citing fentanyl flowing from

China.

February 1 - Trump imposes 10% on goods from China along

with 25% on Mexico and Canada, demanding they curb the flow of

fentanyl and illegal immigrants into the U.S.

February 4 - China responds with a wide range of measures

targeting U.S. businesses including Google, farm equipment

makers and the owner of fashion brand Calvin Klein.

Beijing also slaps levies of 15% on imports of U.S. coal and

LNG and 10% for crude oil and some autos, beginning February 10.

It also restricted exports of five metals used in defence, clean

energy and other industries.

March 3 - The U.S. doubles fentanyl-related tariffs on all

Chinese imports, increasing levies to 20%, effective March 4.

March 4 - China hits back with 10-15% retaliatory levies on

U.S. agriculture exports, affecting about $21 billion in U.S.

exports. Beijing also imposed export and investment curbs on 25

U.S. firms, on grounds of national security and banned imports

of genetic sequencers from U.S. medical equipment maker

Illumina ( ILMN ).

April 2 - Trump escalates global trade friction with

sweeping "liberation day" tariffs, announcing a baseline 10%

across all imports and significantly higher duties on some

countries. Trump levies 34% on all Chinese goods, to take effect

on April 9.

The Trump administration also decides to end duty-free

access for low-value shipments from China and Hong Kong, known

as "de minimis" exemptions, from May 2.

April 4 - China announces retaliatory tariffs of 34% on all

U.S. imports from April 10 and export curbs on some rare earths.

It imposed restrictions on about 30 U.S. organisations, mostly

in defence-related industries.

Beijing also suspends sorghum, poultry and bone meal

shipments from some U.S. firms.

April 8 - The U.S. raises tariff on all Chinese imports to

84% from 34%.

April 9 - China raises levies on U.S. imports to 84% too,

and added 12 U.S. companies to a control list that prohibits

exports of dual-use items and another six to its "unreliable

entities" list, which allows Beijing to take punitive actions

against foreign entities.

The U.S. further hikes tariffs on Chinese imports to 125%

from 84%. China warns its citizens against travelling to the

U.S.

April 10 - China announces it would immediately restrict

imports of Hollywood films.

April 11 - China also raises levies on imports of U.S. goods

to 125%, dismissing the Trump tariff strategy as "a joke" and

indicated it will ignore any further U.S. "numbers game with

tariffs".

April 15 - Chipmaker Nvidia discloses that U.S. officials

had informed it that its H20 chip would require an export

licence for sales to China.

May 10-12 - Beijing and Washington hold trade talks over the

weekend in Geneva. Both sides released a joint statement

agreeing to a 90-day pause on tariffs.

The temporary truce meant U.S. tariffs on China will fall to

30% from 145%, while China tariffs on the U.S. drop to 10% from

125%. China also committed to removing non-tariff

countermeasures imposed against the United States since April 2.

May 28-29 - U.S. says will start "aggressively" revoking

visas of Chinese students. It also orders a broad swathe of

companies to stop shipping goods covering semiconductors, design

software and aviation equipment to China.

May 31 - Trump says China violated agreement reached in

Geneva to mutually roll back tariffs and ease Chinese curbs on

critical minerals exports. China rejects the accusation, saying

U.S. had introduced multiple "discriminatory restrictive"

measures against China.

June 5 - Chinese President Xi Jinping and Trump hold an

hour-long phone call.

June 9-10 - U.S. and China hold a new round of talks in

London and reach a framework agreement.

June 11-12 - Some Chinese rare earths magnet producers begin

to receive export licences. Trump says trade truce is back on

track.

June 27 - Treasury Secretary Scott Bessent says U.S. and

China have resolved issues around rare earth minerals and

magnets shipments to the U.S.

July 6 - Trump threatens an additional 10% tariff on

countries he said were aligning themselves with the

"Anti-American policies" of BRICS, which includes China.

July 15 - U.S. Commerce Secretary Howard Lutnick says Nvidia ( NVDA )

plans to resume sales of its advanced AI H20 chips to China as

part of U.S. negotiations on rare earths, reversing a U.S.

export ban in April.

July 28-29 - U.S. and Chinese officials agree to seek an

extension of their 90-day tariff truce after two days of talks

in Stockholm. Both sides described the talks as constructive,

but no major breakthroughs were announced.

August 1 - Bessent believes Washington has makings of a deal

with China and says is "optimistic" about the path forward.

August 8 - U.S. starts issuing licences to Nvidia ( NVDA ) to export

H20 chips to China.

August 10 - Trump urges China to quadruple its soybean

purchases from the U.S. as the expiration of the trade truce

looms on August 12.

August 11 - U.S. and China extend their tariff truce for

another 90 days.

September 4-13 - Trump and his administration urge the G7,

EU and NATO countries to pressure China and impose tariffs of

50% to 100% to cut off Russian oil revenue.

September 14 - Bessent and China's Vice Premier He Lifeng

lead a fourth round of talks in Madrid to address trade ties as

well as TikTok's looming divestiture deadline on September 17.

September 15 - U.S. and China reach a framework agreement to

switch TikTok to U.S.-controlled ownership, a decision to be

confirmed in a call between Trump and Xi later in the week.

Bessent says Trump administration will not impose additional

tariffs on Chinese goods over Russian oil imports unless

European countries launch tariffs first.
