Even with the wildly low expectations heading into its release, last week's China's December trade report was a horror show, Business Insider Australia's David Scutt wrote.

Then on Monday, China announced its official GDP came in at 6.6% for 2018, the slowest pace of growth since 1990. This was music to the ears of US President Donald Trump who triumphantly tweeted that it made sense now for a battered China to make trade-war concessions.

But compared to 30 years ago, this is a brand-new Chinese economy, under shiny new management.

Winning a trade war with China is not as easy as tweeting about it.

Even with the wildly low expectations heading into its release, China's December trade report was a horror show.

With a US-China trade war in full effect, the value of China's exports and imports imploded by 7.6% and 4.4% respectively from a year earlier, well below market expectations.

"Underlining just how weak the result was, the year-ended percentage decline in both exports and imports was the largest since the second half of 2016, another period when concerns about the Chinese economy were acute," Business Insider Australia's David Scutt wrote.

Then on Monday, China announced its official GDP came in at 6.6% for 2018 — the slowest pace of growth since 1990.

US President Donald Trump took note. Perhaps with an eye to generating concessions out of the ongoing trade war. Trump said this week that it "makes so much sense for China to finally do a real deal," and stop — as he put it — "playing around."

But with the China hawks circling, The Economist encourages a closer look at the world's second-largest economy to better understand why Chinese President Xi Jinping and his economic management team are a good deal calmer than Trump is imagining.

Here are 7 sensible reasons that China is not about to fall over in the face of US tariffs, tweets, or a trade war.

1. It's a question of scale

With an economy now of gargantuan proportions, even at its weakest in 30 years, China’s slower growth last year still generated a record amount of new production. Nominal GDP increased by eight trillion yuan, according to The Economist.

The math is simple: China's economy has been growing in double digits for decades; that means its growth in the present day is coming off a much, much larger base than 2007, when it grew at 14.2% but generated around 3 trillion fewer yuan than 2018's derided 6.6%.

2. China is now a much more self-sustaining economy

A few years ago when China largely made things cheaply and sold them overseas cheaply, a trade war would have been devastating. And while US tariffs still smart, the fall in exports that Scutt called a horror show are less of a bloodbath now than ever before.

So while the trade surplus is slipping, domestic demand easily accounted for the half-percent loss. Domestic consumption, as promised, has been driving Chinese growth; in 2018, it accounted for three-quarters of the growth, the most since 2000, The Economist says.

3. Debt is no longer a secret word

The world's second largest economy expanded 6.5 percent on-year in July-September, National Bureau of Statistics figures showed, in line with an AFP survey, but marking the worst performance since the start of 2009 at the height of the global financial crisis.

China's financial system remains troubled, but it's a mess that is being openly discussed and not hidden in the shadows.

Xi Jinping's government is the first to try and resolve the debt that has risen dramatically in the decade since the Beijing Olympic games.

Debt-to-GDP levels are still rising, but deleveraging was never Xi's goal. That can wait and may be part of an eventual re-nationalization of certain industries. What Xi craves is stability.

The Economist reckons China's pace of debt accumulation has slowed sharply. "In 2015 it took more than four yuan of new credit to generate each yuan of incremental GDP. In 2018 that multiple fell to 2.5, in line with China’s average over the past 15 years."

4. Growth that is in for the long haul

China’s vice-president Wang Qishan has waved away the fears that decades of break-neck growth was always unsustainable, particularly in the face of a US trade war.

"There will be a lot of uncertainties in 2019, but one certainty is that China’s growth will continue and be sustainable,” Wang told the World Economic Forum in Davos, which leads us to China's ace-in-the-hole.

5. Growth that is stage-managed

When Wang says that the Chinese Communist Party will pull out all the stops to maintain the many years of growth China has enjoyed since the 1980s, he knows it's true. China's government and its economy are stage-managed by the same team. When the stock market moves in the wrong direction, the Party has never been too shy to get involved.

6. Actual tax cuts

This year, for example, the government says it will step up fiscal spending to buoy the economy. There is strength enough to deliver further tax cuts and assistance for small business, finance ministry officials told Reuters on Wednesday.

Beijing delivered about 1.3 trillion yuan of cuts in taxes and fees in 2018.

7. Inspired consumption

Consumption in China looks less promising this year, according to The Economist.

"The middle three quintiles of China’s population by income distribution saw earnings increase by only about 2% last year in real terms. Those of the richest quintile rose by 6.6%." Car sales fell last year for the first time in more than two decades. Even mobile phones sales were"sluggish."

But while China brings in a slew of supportive economic policies (like tax breaks) and a stimulus forever on stand-by, the fact is rousing the Chinese consumer for a spree of patriotic spending can be done at the drop of a hat. Or in this case, the word of a president.

One need only look at Jack Ma's Singles Day to understand what can be done when the political and the economic align in today's China.

Trump would do well to consider the previous 30 years of unbroken Chinese growth before he goes into negotiate with a China he imagines has its back against a wall.
