Chinese property developers have turned their sights to Hong Kong's border districts as mainlanders from neighboring boomtown Shenzhen consider parts of the former British colony as a more affordable long-term housing prospect.

The development plans are seen by some as a turning point, with buyers from what was once considered Hong Kong's cheaper industrial hinterland increasingly viewing of the global finance hub as Shenzhen's "backyard."

While Hong Kong's property market remains red-hot, the city's international economic prestige has come under pressure after prolonged pro-democracy protests in 2019 and sweeping new national security laws last year.
