They kicked in just after midnight ET, which is noon in Beijing.
Even though neither Lu nor the Chinese Commerce ministry gave details about the scales of tariffs, Beijing has plans to slap punishing levies 545 USA products worth $34 billion a year that range from soybeans and lobsters to sport utility vehicles and whiskey.
Beijing insists it's the injured party.
On the streets of Beijing, there were some concerns that prices would rise due to the tariffs but also a determination to support the Beijing authorities in the trade war.
With only $130 billion in U.S. imports to retaliate against, Beijing has said it will take "qualitative" and "quantitative" measures against the United States, triggering fears it could cripple the operations of USA multinationals in China.
That would make it America's biggest trade war since the Smoot-Hawley Tariff Act of 1930, at the start of what's now known as the Great Depression. It's very hard for American companies in the auto sector or in financial services to sell into the China market, because there's a lot of regulatory barriers.
Trump needs to be careful that he doesn't go too far and cross a red line and he's very close to doing that right now.
US President Donald Trump last Thursday upped the ante on his country's largest trading partner, warning that the United States may ultimately target more than US$500 billion worth of Chinese goods, roughly the total amount of US imports from China a year ago.
This prompted Beijing to respond with levies on USA imports.

He confirmed that tariffs on $34 billion in Chinese goods would indeed go into effect. "So we have 50 plus 200 plus nearly 300".
The US and China have exchanged the first salvos in what could become a protracted trade war, slapping tariffs on $US34 billion worth of each other's goods and giving no sign of willingness to discuss a truce.
Trump has for years slammed what he describes as Beijing's underhanded economic treatment of the United States in terms of trade, with the U.S. trade deficit in goods with China ballooning to a record $375.2 billion last year. A long list of targeted Chinese products directly purchased by Americans such as TVs, printers and washing machines was sharply revised in June following a trade hearing.
Despite three rounds of negotiations between the two sides, including a Chinese pledge to significantly increase purchases of American products, Trump made a decision to go ahead with the tariffs.
Despite dire warnings about the impact on the US, Trump believes the robust American economy can outlast its rivals in the current battle. United States tariffs on steel and aluminum imports have provoked retaliatory measures against billions of dollars of American exports.
Until now, only $3bn of tariffs have taken effect, but President Trump has threatened new tariffs on many occasions.
'There should be no doubting Beijing's resolve, ' the newspaper said.
China's Ministry of Commerce said the U.S.
From his farm in northeastern China's Happiness Village, Rao Guihe admitted he knows little about President Donald Trump. "It's not clear to anybody, I don't think, what the end game is here, what President Trump hopes to accomplish". The damage could also spread to other economies, hurting business confidence and prompting companies to delay investments.
"Trade war is never a solution", Chinese Premier Li Keqiang said at a news briefing with Bulgarian Prime Minister Boyko Borissov in Sofia before a summit with 16 central and eastern European countries.
The initial tariff threat was once considered by many analysts to be merely a negotiating tactic.
But reaching a deal that's palatable to both sides will be tough.
