India has long been a non-allied country. Amidst rising Sino-American tech competition, India's policy has not changed. It leans towards neither Washington nor Beijing. As India's digital payments sector surges, Chinese and U.S. tech investors shut out from each other's markets are instead competing intensely on the subcontinent. Consolidation will occur as India's digital payments market matures, as it did in the e-commerce, ride-sharing and food-delivery segments, analysts say.

The contrast between WeChat's dominance in mainland China and low profile elsewhere is striking. Of all the markets where WeChat could be a success, Taiwan - with its many cultural similarities to the Chinese mainland - is perhaps the most obvious. Mainland Chinese costume dramas, known for their high production value, are a staple of Taiwanese television. Among smartphone brands, after Apple and Samsung, Oppo, Xiaomi and Huawei are among the most popular with Taiwanese consumers. In e-commerce, Taobao has carved out a strong niche for itself with young Taiwanese, especially women.

Top fintechs all want a piece of the massive Indonesian market, Southeast Asia's largest economy and most populous country with 260 million people. Yet stringent licensing requirements hamper their ability to operate independently. Even giants like Alipay and WeChat Pay are struggling to make their services available to local users. The easiest solution is to find a local Indonesian partner. That's the path WhatsApp is taking as it moves into the Indonesian market, Reuters reported. WhatsApp will reportedly serve as a platform in Indonesia in partnership with local digital wallets.

Singapore-based ride-hailing app Grab intends to become Southeast Asia's premier digital bank, with Vietnam serving as a key growth market. Flush with cash from a recent fundraising round that netted a record $4.5 billion - the most ever for a startup in the region - Grab plans to pour hundreds of billions of dollars into one of Asean's fastest growing economies.

For Thailand, at first blush going cashless seems like a long shot. Cash accounts for 90% of overall transactions in the kingdom, despite 67% of Thailand's population using mobile payments in 2018. Thailand would need to maintain its rapid growth in digital payments over the last two years to make the transition from cash reliant to predominantly digital.

China's fintech giants are best known for dominating their home market. Outside of mainland China, they have limited market share. Merchants in countries popular with Chinese tourists increasingly accept Alipay or WeChat Pay, but the primary users are not locals but Chinese visitors who want to pay by smartphone as they do at home.

In Cambodia, however, Chinese fintechs have a chance to gain a strong foothold in the local payments market. To be sure, Cambodia's efforts to boost financial inclusion are a key reason for that. The Cambodian government sees digital banking as an efficient way to bring the kingdom's large unbanked population (estimated by the World Bank at 78% of Cambodians aged 15 and up) into the formal financial system. Further, commercial ties are burgeoning between Beijing and Phnom Penh. China is Cambodia's largest investor and source of tourists. That has opened up opportunities for Alipay and WeChat Pay to partner with local firms.

Chinese fintech giant Alipay has been on a torrid expansion streak, entering global markets from the U.S. and Europe to Bangladesh and Pakistan. Now Alipay is pushing even further into emerging markets as it establishes a partnership with fintech startup Flutterwave to provide digital payments services between the Middle Kingdom and Africa.

When it comes to Indonesia's digital wallets, Go-Jek's Go-Pay captures many of the headlines. After all, Go-Jek is Indonesia's most prominent unicorn, valued at US$9-10 billion. It's battling Singapore's Grab across Southeast Asia, burning piles of cash as investors rush to join the next round of fundraising. Speculation about a Go-Jek IPO is mounting.

Yet Indonesian consumers prefer a different digital wallet, according to local research firm Snapcart. Data compiled by the Indonesia-based company show that Ovo, backed by Grab and the Lippo Group, is the top Indonesian mobile wallet by a wide margin. Ovo holds a 58% market share, compared to Go-Pay's 23% and Emtek Group and Ant Financial's DANA, a distant third at 6%.

India has one of Asia's most vibrant fintech ecosystems, highlighted by payments unicorn Paytm with a valuation of US$10 billion. In the first quarter of the year, the subcontinent attracted the most VC fintech investment of any country in Asia, beating out digital finance juggernaut China.

Given the excitement surrounding India's fintech scene, it is easy to overlook cash's continued paramountcy in the Indian economy, accounting for 95% of transactions. Indeed, cash not only remains the primary payment method in India, its use is growing. The reason is straightforward: Cash is convenient - especially considering India's large informal economy. The fintech ecosystem must penetrate far deeper into the Indian economy before it can begin to displace cash.

The Philippines is steadily adopting digital payments as part of a state-led drive to boost financial inclusion. The number of active e-wallet accounts in the country rose 22% annually in 2018 to reach 33 million, according to data compiled by Bangko Sentral ng Pilipinas (BSP), the Philippines' Central Bank. E-wallet growth last year edged out credit card growth, which rose 18% to 9.4 million users compared to a year earlier.

The Philippines is poised to reduce its dependency on cash - which accounted for 99% of transactions in 2018 - thanks to high smartphone penetration, strong demand from a large unbanked population and consumer willingness to bank digitally. Additionally, with their low barriers to entry, digital wallets are a good way to support financial inclusion.
