How has China contributed toward the conclusion of the Regional Comprehensive Economic Partnership (RCEP)? The extant literature tends to either undervalue China's role or emphasizes the absence of China's willingness to realize the RCEP. However, it is difficult to form region-wide multilateral preferential trade agreements (PTAs), such as RCEP, without any significant contribution from a regional hegemon, such as China. This paper, thus, argues that China has contributed significantly toward the conclusion of RCEP by engendering incentives for member countries to join through multiple cooperative structures. These cooperative structures involve China-led bilateral PTAs and international development forums, which include the Belt and Road Initiative and Asian Infrastructure Investment Bank. With the gradual shift from bilateral to multilateral PTAs and forum-linkage strategies, China turned to be more assertive in concluding the RCEP than in the early years of RCEP negotiations, as evidenced by the discourse of political and opinion leaders.

Trimetallic selenides as bifunctional electrocatalysts for oxygen evolution reaction (OER) and urea oxidation reaction (UOR) have rarely been reported. Herein, we successfully synthesized nickel-iron-cobalt diselenides on the nickel foam (NiFeCoSe2) by a one-step electrodeposition method. The as-prepared NiFeCoSe2 nanosheets on nickel foam (NF) exhibited significantly improved electrocatalytic performance and stability in a highly alkaline medium (1 M KOH) with and without 0.33 M urea. In particular, the obtained NiFeCoSe2 only requires a potential of 1.52 V (vs. RHE) for OER and 1.37 V (vs. RHE) for UOR to achieve a current density of 50 mA cm−2, along with a stability of 30 h. This was attributed to the unique interconnected nanosheets, binder-free in-situ selenium electrodeposition, synergistic effect, and strong electron interaction of Ni, Fe, Co, and Se elements. This study provides a new avenue for the construction of multimetal selenide electrocatalysts with excellent properties for the oxidation of water and urea. ; This work was supported by the Human Resources Development Program (No. 20194030202470) of the Korea Institute of Energy Technology Evaluation and Planning (KETEP) Grant funded by the Korean Government Ministry of Trade, Industry, and Energy and supported by the Priority Research Centers Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education, Science and Technology (2018R1A6A1A03024334).
