Chinese state media have stepped up anti-US propaganda after Trump threatened to slap tariffs on 'at least' another $300 billion worth of Chinese goods.

China's state news agency Xinhua today said Beijing must never surrender to the U.S. in the trade war against Trump.

In the latest commentary, Xinhua compared the tariff war with the real war between China and Japan in the 1930s and 40s indirectly, and vowed that China would never back off.

China blasted the U.S. today in two commentaries through two separate state news outlets after Trump threatened to slap tariffs on 'at least' another $300 billion worth of Chinese goods

'If we don't fight, enemy will kill us with a bayonet,' wrote the article, quoting a chilling war poem from the second Sino-Japanese War, a part of World War II.

'[They] will then point at our bones with their fingers and say: "Look, these are slaves,"' the poem continued.

The column also blasted a number of 'Washington worshippers' in China who think Beijing should give in because it couldn't win the tariff battle.

'To this, we must say "no" resolutely,' urged the author.

A separate column today, People's Daily, the mouthpiece of China's Communist Party, said 'stubborn' Washington politicians are leading the U.S. astray.

'America doesn't have the right or the power to scrap everything and start from scratch for its own benefit,' it condemned.

The paper added: 'For certain American politicians, no matter how they act, they can't blind people in the world with lies.'

Both commentaries come after U.S. President Donald Trump yesterday threatened to hit China with tariffs on 'at least' another $300 billion worth of Chinese goods.

Trump also said he would make a decision on the tariffs until he speaks to Chinese President Xi Jinping this month in Osaka.

Trump and Xi are attending the Group of 20 Summit at the month in Japan. The U.S. president has committed to meeting with his Chinese counterpart to discuss their continuing trade war.

'I make that decision in the next two weeks after the G20. I will be meeting with President Xi and we'll see what happens,' he declared. 'We're probably planning it sometime after G20.'

Chinese state media have been ratcheting up anti-U.S. rhetoric since the two countries failed to reach an agreement at trade talks earlier this month and Trump more than doubled punitive tariffs on $200 billion (£158 billion) worth of Chinese goods to 25 per cent.

Beijing imposed new tariffs on 5,410 American products from June 1 in retaliation.

The tariffs, ranging from five percent to 25 per cent, impact various common items including condoms, perfume, wine, pianos, cordless phones, industrial robots, coffee and ovens.

'If the perpetrator wants to fight, we will beat him out of his wits,' the lyrics of the privately produced song titled Trade War read. It has gathered more than 3.2 million views on WeChat

Chinese state-run commentaries have branded Washington as 'a liar', 'a bully' and 'enemy of the world'.

Chinese web users echoed the propaganda by promoting an anti-U.S. viral song to support Beijing during the trade war.

'If the perpetrator wants to fight, we will beat him out of his wits,' read the lyrics of the privately produced song, titled Trade War.

Earlier this week, Chinese authorities issued two separate travel warnings for the U.S., advising citizens to avoid trips to America.

The Foreign Ministry said in its travel alert that Chinese citizens had been interrogated, interviewed and subjected to other forms of what it called harassment by U.S. law enforcement agencies repeatedly.

While the Ministry of Culture and Tourism claimed the U.S. saw high frequency of shootings, robberies and theft as it cautioned Chinese tourists.

Chinese students were also warned to think twice before deciding to study in the U.S. by the Ministry of Education due to 'visa concerns'.
