Other highly focused bond ETFs have quickly gained investors’ attention. The Market Vectors ChinaAMC China Bond ETF (NYSEArca: CBON) and the Global X GF China Bond ETF (NYSEArca: CHNB) debuted within days of each other last month, becoming the first ETFs to give U.S. investors access to China’s massive onshore bond market. In barely more than a month of trading, CBON and CHNB have attracted a combined $72.5 million in assets.

The KraneShares E Fund China Commercial Paper ETF (NYSEArca: KCNY) followed, debuting on Dec. 3. KCNY, the first Chinese commercial paper ETF to list in the U.S., features an average maturity of just 128 days and a lineup comprised entirely of investment-grade holdings and tracks the CSI Diversified High Grade Commercial Paper Unhedged Index. [A Cash Stash ETF for 2015]

Translation: KCNY can be used as a money market alternative without the meager interest rates offered by U.S. money markets. Chinese money markets have delivered 4.9% over the past year, according to KraneShares. Investors have allocated almost $22.5 million to KCNY.
