インドネシアの工場でトラブルがあり、解決のためナガイはインドネシアへ行っています。
ですのでベトナム行きの予定が遅れています。
来月予定が組めたらまたご連絡しますとのことです。
As there were some troubles with the factory at Indonesia, to resolve the issues, Nagai had went over to Indonesia.
As such, the scheduled Vietnam trip would be delayed.
I would contact you again when the schedule has been confirmed next month.
