Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

Geological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Knowledge sourcing, geopolitics, and FDI: An empirical analysis on the US green and digital sectors

Global Strategy Journal, EarlyView.
Abstract Research Summary This paper examines how foreign direct investment (FDI) shapes firms' sourcing of knowledge in the digital and green domains under rising geopolitical frictions. We assemble a firm–country dyadic panel (2013–2020) linking US patent backward citations to firms' FDI, enriched with bilateral geopolitical distance and host‐country

Rethinking a positive‐sum game: US FDI location decisions in the presence of Chinese FDI

Global Strategy Journal, EarlyView.
Abstract Research Summary This study examines how rising Chinese outbound foreign direct investment (OFDI) in third‐country markets shapes US MNEs' foreign direct investment location decisions amid escalating US–China geopolitical rivalry. US firms initially benefit from complementary co‐location dynamics, as Chinese OFDI—particularly in infrastructure—
