Nov 7 (Reuters) - Donald Trump has been elected U.S.

president, capping a remarkable comeback four years after he was

voted out of the White House.

Here is what companies in Asia have invested in the United

States, what Trump has said about them and what potential U.S.

business policy changes would mean for Asian companies.

SEMICONDUCTORS

Asian chipmakers, led by Taiwan's TSMC and South

Korea's Samsung Electronics ( SSNLF ), have announced plans to

invest at least $117 billion in the U.S. in total, encouraged by

the current U.S. administration's key initiative aimed at

lowering its reliance on Asia for high-end chips.

In return, they have received or been pledged grants and

financial support amounting to at least $18.85 billion,

according to Reuters' calculation.

It's unclear if Trump would roll back the scheme, which he

called "bad." He made comments on the campaign trail that

Chinese-claimed Taiwan should pay to be protected and also

accused the island of stealing business from American

semiconductor companies.

Taiwan's GlobalWafers said on Thursday it expects

the subsidy programme to continue in a Trump administration.

ELECTRIC VEHICLES

Trump has floated the idea of a 10% or more tariff on all

goods imported into the U.S., a move he says would eliminate the

trade deficit.

He has also threatened a 200% tariff on some imported cars,

and is particularly determined to keep cars from Mexico from

coming into the country. The tariff would hit multiple Asian

automakers including Honda Motor ( HMC ), Nissan Motor ( NSANF )

and Kia Corp. ( KIMTF )

Honda ( HMC ) chief operating officer Shinji Aoyama warned on

Wednesday that tariffs on vehicles imported from Mexico would

have a huge impact as the company sends 80% of its production

there to the U.S. market.

He said if such measures became permanent, Honda ( HMC ) would have

to consider shifting production to the U.S. or another

tariff-free country in the long run.

EV BATTERIES

South Korean battery makers and Japan's Panasonic ( PCRFF ),

which have multiple EV battery factories operating in the United

States, are now bracing for a potential roll back of President

Joe Biden's signature clean energy policy and looser emissions

regulations.

Trump told Reuters in August that he may eliminate a $7,500

tax credit for EV purchases.

Since 2023, LG Energy Solution and SK On have

received 2.6 billion won ($1.9 million) in U.S. federal credits

for making battery cells in the United States, according to

Reuters' calculation based on their stock exchange filings.

Without those manufacturing credits, they would have posted

losses, the companies said.

However, U.S. restrictions on Chinese batteries may remain

in place or toughen under a second Trump administration, a

policy that would benefit rival South Korean producers.

NIPPON STEEL ( NISTF )

The U.S. government has yet to approve Nippon Steel's ( NISTF )

$14.9 billion bid for U.S. Steel, a politically

sensitive deal due to opposition from the U.S. firm's labour

union.

Trump has said he would block the deal, as he has sought to

woo union voters. Biden has also said he is opposed to the

takeover.

The Committee on Foreign Investment in the United States

said in August the deal posed a risk to national security as it

threatened the steel supply chain for critical U.S. industries,

prompting Nippon Steel ( NISTF ) to pledge investments worth billions in

U.S. Steel facilities that otherwise would have been idled.

CHINA

Chinese businesses are waiting to see if Trump makes good on

a threat to impose tariffs of 60% or more on imports from China,

which could kickstart a fresh trade war reminiscent of the one

he waged during his 2017-2021 presidency.

The trade war hit sectors across the board, from

manufacturers of vacuum cleaners to machinery, with tariffs

imposed on more than $200 billion of goods. The Biden

administration has kept most of the tariffs in place.

Several Chinese companies were also hit with export controls

by the Trump administration citing national security, such as

Huawei Technologies which was barred from purchasing high-end

chips, crippling its smartphone business.

Other Chinese tech firms targeted include ByteDance and

Tencent ( TCTZF ), whose respective TikTok and WeChat social

media apps came under threat of being banned from operating in

the U.S.

Some Chinese exporters are making plans to accelerate

relocation or open factories outside China to cope with Trump's

return.

But some Chinese tech executives are betting that Trump's

combative approach could work in their favour, as U.S. efforts

to slow China's technological progress might fail to gain

international support.

Nazak Nikakhtar, a Commerce Department official under Trump

who knows his current advisers, said she expects a Trump

administration to be much more aggressive about export control

policies towards China.
