NEW DELHI: TikTok on Tuesday denied sharing users鈥� data with the Chinese government, after India banned the wildly popular app as ties with Beijing deteriorate sharply following a deadly border clash.

Blaming each other for the brutal hand-to-hand battle on June 15 as talks make little headway, the Asian giants have been bolstering their border forces as anti-China sentiment grows in India.

As India reportedly considered hiking tariffs and with some Chinese imports held up at ports, Prime Minister Narendra Modi鈥檚 government on Monday banned 59 Chinese apps including TikTok, WeChat and Weibo.

The ministry of information technology said the apps 鈥渁re engaged in activities ... prejudicial to sovereignty and integrity of India, defense of India, security of state and public order.鈥�

The move mirrored growing unease about Chinese tech firms in other countries, in particular regarding telecom giant Huawei.

TikTok, owned by China鈥檚 ByteDance, allows users to upload and share short videos and is spectacularly popular in India 鈥� its 120 million users have made it the app鈥檚 top international market.

On Tuesday, the head of TikTok India issued a statement saying the firm has 鈥渘ot shared any information of our users in India with any foreign government, including the Chinese government.鈥�

鈥淔urther if we are requested to in the future we would not do so,鈥� Nikhil Gandhi said, adding that 鈥渉undreds of millions of users, artists, story-tellers, educators and performers ... (depend) on it for their livelihood.鈥�

It remains unclear, however, how the bans would work, with Indians who have downloaded TikTok on their phones still able to use the app on Tuesday.

China and India have long had a prickly relationship.

But the border clash was the first deadly violence on their disputed Himalayan border in 45 years, claiming the lives of 20 Indian soldiers. Chinese casualties are unknown.

The Indian deaths triggered outrage on social media with calls to boycott Chinese products. Chinese flags were set on fire and traders destroyed Chinese goods at scattered street protests.

Ties were strained last August when New Delhi revoked the semi-autonomous status of Indian-controlled Kashmir and split off Ladakh 鈥� parts of which are claimed by China 鈥� into a new administrative territory.

India shares US unease about growing Chinese influence in the Indian Ocean and New Delhi has bolstered defense cooperation with Washington as well as Australia and Japan.

India has also been irked by China鈥檚 backing of arch-rival Pakistan and the construction of an economic corridor going through parts of Kashmir controlled by Islamabad but claimed by India.

Since the latest clash, the nuclear-armed neighbors have reinforced the border between Ladakh and Tibet. India has deployed thousands more troops and is conducting extra military flights over the mountainous region.

鈥淭hose who cast an evil eye on Indian soil in Ladakh have got a befitting response,鈥� Modi said in his weekly radio address on Sunday.

He was due to address the nation again at 4:00 p.m. on Tuesday.

With Asia鈥檚 third-biggest economy dealt a sucker punch by the coronavirus, the apps ban fits in with Modi鈥檚 vision outlined in May of a 鈥渟elf-reliant India鈥� able to produce all it needs at home.

But New Delhi has a trade deficit of around $50 billion with China, with India鈥檚 pharmaceutical, electronics and automotive sectors hugely reliant on imports of Chinese raw materials and components.

Chinese electronic firms also have a major presence in India, with cellphone brands like Xiaomi 鈥� which manufactures in India 鈥� enjoying a market share of almost 65 percent.

The ban on the apps 鈥渋s fine as a gesture of protest but we should be very careful with escalation right now,鈥� said Manoj Joshi from the Observer Research Foundation, an Indian think tank.

鈥淩ight now I don鈥檛 think there are any easy options for New Delhi.鈥�
