Tokyo:

Some Asian countries stand to gain if US president-elect Donald Trump pushes ahead with his promised massive tariffs on China and triggers a new wave of factory relocations to the rest of the region.

But a trade war between the world's biggest economies would also destabilise markets everywhere, with Asia -- which contributes the largest share of global growth -- the most affected.

Trump, who won a crushing presidential victory this week, vowed during his campaign to slap 60 per cent tariffs on all Chinese goods entering the United States in an attempt to balance trade between the two nations.

Analysts however question whether the new president will stick to such a high figure, and dispute the blow such tariffs could inflect on the Chinese economy, estimating GDP could be lowered by between 0.7 per cent and 1.6 per cent.

The cooling effect would also make waves throughout Southeast Asia, where production chains are closely linked to China and enjoy significant investment from Beijing.

"Lower US demand for Chinese goods due to higher tariffs on China will translate into lower demand for ASEAN exports, even if there aren't US tariffs levied directly onto those economies," said Adam Ahmad Samdin, of Oxford Economics.

Indonesia is particularly exposed through its strong exports of nickel and minerals, but China is also the top trading partner of Japan, Taiwan and South Korea.

In addition to China, Donald Trump has also warned of an increase of 10 to 20 per cent on duties for all imports, as part of his protectionist policies and fixation that other countries take advantage of the US.

"The extent of these effects likely depends on the direct exposure of each economy to the US," said Samdin, who added that America accounts for a 39.1 per cent share of Cambodian exports, 27.4 per cent from Vietnam, 17 per cent from Thailand and 15.4 per cent from the Philippines.

India to be targeted? 

Trump first slapped China with heavy tariffs in 2018 during his first administration, leading to the emergence of "connector countries", through which Chinese companies passed their products to avoid American taxes.

Those countries could be in the line of fire now.

Vietnam's electronics exports to the US could also be targeted by Trump, in a bid to halt the diversion of Chinese electronic products to the US via Vietnam since 2018," said Lloyd Chan, a senior analyst at MUFG, Japan's largest bank.

"This is not inconceivable. Trade rewiring has notably gained traction in the region's electronics value chain."

"India could itself become a target of protectionist measures by the US due to the large share of Chinese components in Indian products," added Alexandra Hermann, an economist with Oxford Economics.

Trump could also impose higher tariffs on Indian goods in sectors such as "automobiles, textiles, pharmaceuticals and wines, which could make Indian exports less competitive in the US", said Ajay Srivastava of the New Delhi-based Global Trade Research Initiative.

A trade war would be dangerous for India, said Ajay Sahai, director of the Federation of Indian Export Organisations.

"Trump is a transactional person. He may target higher tariffs on certain items of Indian exports so he can negotiate for lower tariffs for US products in India," he told AFP.
